Federal judge orders end to National Guard deployment in DC
A federal judge is ordering the Trump administration to end its monthslong deployment of National Guard troops to help police the nation’s capital.

Quantum Coherence in a Maximally Hot Hubbard Chain
We present a detailed study of the real-time dynamics and spectral properties of the one-dimensional fermionic Hubbard model at infinite temperature. Using tensor network simulations in Liouville space, we compute the single-particle Green's function and analyze its dynamics across a broad range of interaction strengths. To complement the time-domain approach, we develop a high-resolution Chebyshev expansion method within the density matrix formalism, enabling direct access to spectral function…

Two-dimensional (2D) magnets host a wide range of exotic magnetic textures, whose low-energy excitations and finite-temperature properties are typically described by effective spin models based on Heisenberg-like Hamiltonians. A key challenge in this framework is the reliable determination, from ab initio calculations, of exchange parameters and their anisotropic components, crucial for stabilising long-range order. Among the different strategies proposed for this task, the energy-mapping metho…

We report on an experimental investigation of the interplay between friction, adhesion, contact geometry, and finite strains for smooth frictional contacts between rigid spherical glass probes and flat silicone substrates. Using both bulk and layer substrates under various loading conditions (normal force, radius of the probe), we show that shear-induced anisotropic shrinkage of the adhesive contact area under steady-state sliding is an effect of finite-elasticity conditions and is drastically …

A follow-up on the sulphur atom popping model for MoS$_2$ memristor
The mechanism of resistive switching in two-dimensional (2D) semiconductor-based memristors is intriguing, and our conventional knowledge of bulk-oxide based memristors does not apply to these devices. Experimental data indicate that the genesis of resistive switching may be intrinsic to the 2D semiconducting active layer, as well as resulting from the movement of electrode atoms. Employing reactive-force field (ReaxFF) molecular dynamics simulations, we introduced the "sulphur atom popping mod…

Random close packing fraction of bidisperse discs: Theoretical derivation and exact bounds
A long-standing problem has been a theoretical prediction of the densest packing fraction of random packings, $Φ_{RCP}$, of same-size discs in $d=2$ and spheres in $3$. However, to minimize order, experiments and numerical simulations often use two-size discs. For practical purposes, then, a predictive theory for the packing fraction, $Φ_{RCP}$, of the densest such bidisperse packings is more useful. A disorder-guaranteeing theory is formulated here to fill this gap, using an approach that le…

The more intricate the molecular organization, the more complicated the corresponding diffraction pattern is. To the point where standard analysis, i.e., identifying peak positions and solving the crystal structure, …

Quantitative description of the surface tension minimum in a two-component surfactant system
The Gibbs adsorption equation is the thermodynamic cornerstone for the description and understanding of the surface tension in a surfactant solution. It relates the decrease in surface tension to an increased surfactant adsorption. In the early 1940's, it therefore puzzled researchers to sometimes observe a minimum in the surface tension for certain surfactant solutions, which seemed to indicate surfactant desorption (even depletion) according to the Gibbs adsorption equation. It is now underst…

Glassy dynamics in two-dimensional ring polymers: size versus stiffness polydispersity
Soft glassy materials often consist of deformable objects. Here, we use a two-dimensional assembly of semi-flexible ring polymers as a model system to investigate how polydispersity in particle stiffness or size influences the onset of glassy dynamics. In simulations at fixed polydispersity 30%, we find that stiffness dispersity drives most rings into elongated conformations at high densities, leading to orientationally ordered structures that cause dynamical slowing down. In contrast, size dis…

Within the relaxation-time approximation, we predict experimentally accessible signal magnitudes. T…

Living Droplets with Mesoscale Swimmers
We study the activity of "living" droplets, which confine 1-6 mesoswimmers in 3D using a superhydrophobic substrate. The swimmers induce oscillations of the droplets at their inherent resonant frequencies, regardless of swimmer size and number. In contrast, the droplet oscillation amplitude is strongly affected by crowding, which we successfully model with a new scaling law and show that crowding reduces the speed of the swimmers. These fundamental living matter physics results reveal mechanism…

Non-relativistic spin splitting in antiferromagnets has recently attracted considerable attention. Here we present a universal framework for controlling such spin splitting by identifying and manipulating the key atomic distortions that govern it through external perturbations. We demonstrate this concept by tuning the spin-splitting energy in three representative materials with diverse symmetries, inversion-symmetric MnF$_2$, ferroelectric BaCuF$_4$, and LaMnO$_3$/RMnO$_3$ superlattices.

We introduce a design principle for mechanical metamaterials based on "odd elasticity, once removed." By revisiting classic results relating the variation of Cauchy stress and Lagrangian strain around a prestressed reference state, we show how anisotropic, equilibrium prestress can generate a major anti-symmetry in the material's constitutive response. Tuning the system to such a state drives it to a critical instability, radically transforming its acoustic properties. We then inverse-design se…

Intrinsic defect intolerance in the ultra-pure metal PtSn$_4$
Ultra-pure materials are highly valued as model systems for the study of intrinsic physics. Frequently, however, the crystal growth of such pristine samples requires significant optimization. PtSn$_4$ is a rare example of a material that naturally forms with a very low concentration of crystalline defects. Here, we investigate the origin of its low defect levels using a combination of electrical resistivity measurements, computational modeling, and scanning tunneling microscopy imaging. While t…

Particle-scale studies elucidating visco-collisional rheology in granular-fluid flows
We study the particle-scale dynamics that give rise to bulk flow behaviours of highly concentrated particle-fluid mixtures using discrete element method (DEM) simulations. We utilize boundary conditions of a stress-controlled shear cell and vary material properties and applied stresses systematically. We find the bulk rheology transitions smoothly among what might be called viscous, collisional, and visco-collisional behaviours based on average shear rate dependence as well as dominance of loca…

Analytical analysis of the spin wave dispersion in the cycloidal spin structures under the influence of magneto-electric coupling
Spin waves and coupling of the spin waves with electromagnetic waves are considered in the multiferroic materials with the electric dipole moment proportional to the scalar product of spins. Dispersion dependence for the spin waves propagating as the perturbation of the equilibrium state described by spin cycloid is found. The dielectric permeability as the response on the electromagnetic perturbations associated with the magneto-electric coupling for the same equilibrium state is calculated.

Tunable Electronic Interactions and Weak Antilocalization in Bulk Ge$_2$Sb$_2$Te$_{5-5x}$Se$_{5x}$ Phase Change Materials
Phase change materials (PCMs) are well-known for their reversible and rapid switching between crystalline and amorphous phases through thermal excitations mediated by strong electrical or laser pulses. This crystal-to-amorphous transition is accompanied by a remarkable contrast in optical and electronic properties, making PCMs useful in nonvolatile data storage applications. Here, we combine electrical transport and angle resolved photoemission spectroscopy (ARPES) measurements to study the ele…

Cooperative Function with Thermal Fluctuations in Mechanical Networks
Elastic networks can be tuned to exhibit complex mechanical responses and have been extensively used to study protein allosteric functionality, where a localized strain regulates the conformation at a distant site. We show that cooperative binding, where two sites each enhance the other's ability to function, can be trained via a symmetric application of the training previously employed for creating network allostery. We identify a crossover temperature above which cooperative functionality bre…

Artificial ferroelectric-like hysteresis in antiferroelectrics with non-uniform disorder
Antiferroelectrics exhibit unique double-hysteresis polarization loops, which have garnered significant attention due to their potential applications such as energy storage, electromechanical transduction, as well as synapse devices. However, numerous antiferroelectric materials have been reported to display signs of hysteresis loops resembling those of ferroelectric materials, and a comprehensive understanding remains elusive. In this work, we provide a phenomenological model that reproduces s…

Fundamental Scaling Constraints for Equilibrium Molecular Computing
Molecular computing promises massive parallelization to explore solution spaces, but so far practical implementations remain limited due to off-target binding and exponential proliferation of competing structures. Here, we investigate the theoretical limits of equilibrium self-assembly systems for solving computing problems, focusing on the directed Hamiltonian Path Problem (HPP) as a benchmark for NP-complete problems. The HPP is encoded via particles with directional lock-key patches, where s…

Topological nontrivial berry phase in altermagnet CrSb
The study of topological properties in magnetic materials has long been one of the forefront research areas in condensed matter physics. CrSb, as a prototypical candidate material for altermagnetism, has attracted significant attention due to its unique magnetic properties. This system provides a novel platform for exploring the intrinsic relationship between altermagnetic order and exotic topological states. In this study, we combine systematic electrical transport experiments with first-princ…

Low Temperature MOCVD Synthesis of high-mobility 2D InSe
Two-dimensional (2D) indium selenide (InSe) is a layered semiconductor with high electron mobility and a tunable band gap ranging from 1.25 eV in the bulk to 2.8 eV in the monolayer limit. These properties make these materials strong candidates for future logic and optoelectronic devices. However, growing phase-pure InSe remains challenging due to the complex indium-selenium (In-Se) phase diagram. This complexity and the sensitivity of chemical precursors to growth conditions make it difficult …

Avalanche-like lithium intercalation and intraparticle correlations in graphite
Graphite is the most widely used anode material in lithium-ion batteries with over 98% market share. However, despite its first application over 30 years ago, the lithium insertion processes and associated dynamics in graphite remain poorly understood, especially for the dilute stages. A fundamental understanding of how the symmetry-breaking phase transitions occur pseudo-continuously under operating conditions is still lacking. Here, we provide a unified picture of ion intercalation dynamics d…

A GND-based back stress model for reverse loading in metal sheets with consideration of GNB
Accurate prediction of springback and formability in sheet metal forming requires understanding reverse loading behavior under complex loading path changes, such as tension followed by compression. However, for ultra-thin sheets experimental characterization of such behavior is difficult due to compressive instability like plastic buckling. This study presents a crystal plasticity finite element method (CPFEM) incorporating a physically motivated back stress model based on geometrically necessa…

Computing finite--temperature elastic constants with noise cancellation
Elastic constants are central material properties, frequently reported in experimental and theoretical studies. While their computation is straightforward in the absence of thermal fluctuations, finite--temperature methods often suffer from poor signal--to--noise ratios or the presence of strong anharmonic effects. Here, we show how to compute elastic constants in thermal ordered and disordered systems by generalizing a noise--cancellation method originally developed for piezoelectric coupling …

SMC-X: A Distributed Scalable Monte Carlo Simulation Method for Chemically Complex Alloys
To predict the complex chemical evolution in multicomponent alloys, it is highly desirable to have accurate atomistic simulation methods capable of reaching sufficiently large spatial and temporal scales. In this work, we advance the recently proposed SMC-X method through distributed computation on either GPUs or CPUs, pushing both spatial and temporal scales of atomistic simulation of chemically complex alloys to previously inaccessible scales. This includes a 16-billion-atom HEA system extend…

Defect-Charge-Driven 90° Switching in HfO2
Hafnium dioxide (HfO2) is a CMOS-compatible ferroelectric showing both 180° and 90° switching, yet the microscopic nature of the 90° pathway remains unresolved. We show that the 90° rotation pathway, negligible in pristine HfO2, becomes dominant under E// [111] when induced by charged oxygen vacancies. This pathway is more fatigue-resistant than the 180° reversal pathway, while delivering the same polarization change along [111] (2Pr=60 μC/cm^2 ). This charge-driven switching arises from …

Uniaxial negative thermal expansion in a weak-itinerant-ferromagnetic phase of CoZr$_{2}$H$_{3.49}$
We discovered unique uniaxial negative thermal expansion (NTE) behavior for a weak-itinerant-ferromagnetic phase of CoZr$_{2}$H$_{3.49}$. CoZr$_{2}$ is known as a superconductor exhibiting uniaxial NTE along the $c$-axis, which is called anomalous thermal expansion (ATE). Additionally, CoZr$_{2}$ is also known as a well-absorbent of hydrogen, and hydrogen insertion raises weak-itinerant ferromagnetism instead of superconductivity. However, the influence of hydrogen insertion on ATE behavior in …

Magnetic order tuning of excitons in the magnetic semiconductor CrCl$_3$ through strain
Magnon-exciton coupling provides an unprecedented opportunity for the optical tunability of spin information and, viceversa, for the magnetic control of the optical response. Few-layered magnets are an ideal platform for the experimental study of this coupling, in part due to the strong excitonic character of the optical response in (quasi-)two dimensions. Here, we demonstrate a strong dependence of the excitonic oscillator strength on the magnetic order in a monolayer of chromium trichloride C…

Intrinsic antiferromagnetic half-metal and topological phases in the ferrovalley states of the sliding bilayer altermagnets
Altermagnetism is characterized by non-relativistic spin splitting and zero total magnetic moments. In this work, intrinsic antiferromagnetic half-metallic and topological phases were discovered within the ferrovalley states of sliding bilayer altermagnets. We construct the bilayer system by utilizing altermagnet monolayers with a small bandgap. The inter-layer hopping phenomenon leads to a reduction in bandgaps, and sliding engineering induces ferrovalley states. Taking the V$_2$OSSe system fo…

Robust Ferrimagnetic Ground State and Suppressed Superconductivity in Two-Dimensional HC6
Two-dimensional hydrogenated graphene (HC6) represents a promising platform for exploring emergent electronic phases. Owing to its high electronic density of states at the Fermi level, HC6 is expected to support phonon-mediated superconductivity, with a calculated critical temperature Tc of 37.4 K in the paramagnetic metallic phase. However, spin-polarized first-principles calculations reveal that HC6 stabilizes in a ferrimagnetic ground state, which is energetically favored by 0.175 eV per uni…

Accurate understanding and control of interfacial adhesion between Cu and Ta$_x$N diffusion barriers are essential for ensuring the mechanical reliability and integrity of Cu interconnect systems in semiconductor devices. Amorphous tantalum nitride (a-Ta$_x$N) barriers are particularly attractive due to their superior barrier performance, attributed to the absence of grain boundaries. However, a systematic atomistic investigation of how varying Ta stoichiometries influences adhesion strength at…

Negative Charge Transfer: Ground State Precursor towards High Energy Batteries
Modern energy applications, especially electric vehicles, demand high energy batteries. However, despite decades of intensive efforts, the highest energy density and commercially viable batteries are still based on LiCoO2, the very first generation of cathode materials. The technical bottleneck is the stability of oxide-based cathodes at high operating voltages. The fundamental puzzle is that we actually never understood the redox mechanism of LiCoO2. Conventional wisdom generally defines redox…

In all three schemes, single-phase compounds can be obtained over a wide range …
