Bubble Dynamics Transformer: Microrheology at Ultra-High Strain Rates
Laser-induced inertial cavitation (LIC)-where microscale vapor bubbles nucleate due to a focused high-energy pulsed laser and then violently collapse under surrounding high local pressures-offers a unique opportunity to investigate soft biological material mechanics at extremely high strain rates (>1000 1/s). Traditional rheological tools are often limited in these regimes by loading speed, resolution, or invasiveness. Here we introduce novel machine learning (ML) based microrheological framewo…

Bayesian Model Selection and Uncertainty Propagation for Beam Energy Scan Heavy-Ion Collisions
We apply the Bayesian model selection method (based on the Bayes factor) to optimize $\sqrt{s_\mathrm{NN}}$-dependence in the phenomenological parameters of the (3+1)-dimensional hybrid framework for describing relativistic heavy-ion collisions within the Beam Energy Scan program at the Relativistic Heavy-Ion Collider. The effects of various experimental measurements on the posterior distribution are investigated. We also make model predictions for longitudinal flow decorrelation, rapidity-depe…

Ultrafast Optical Evidence of Split Density Waves in Bilayer Nickelate La$_3$Ni$_2$O$_7$
Utilizing ultrafast optical pump-probe spectroscopy, we investigated the quasiparticle and spin dynamics in single crystals of bilayer nickelate La$_3$Ni$_2$O$_7$. Our experimental results unequivocally demonstrate the presence of two distinct density wave (DW)-like orders, manifesting with onset temperatures at $\sim$140 K and $\sim$115 K. Through time-resolved ellipticity measurements, we identified the higher-temperature order at 140 K ($T_{\rm SDW}$) as the onset of a spin density wave (SDW…

Všžené čtenšřky a čtenšři,
doufšm, že si užívšte léto a aspoň na chvíli můžete vypnout od školy, pršce a čšstečně třeba i od neustšlého proudu dění v divokém světě. Když každý rok s úderem července klesnou čísla nšvštěv webu, otevíršní newsletterů nebo přehršvšní videí a jš jsem v tu chvíli za všs ršd, že můžete mít aspoň chvíli klid. A trochu všm zšvidím ☺️

Prediction of several Co-based La$_3$Ni$_2$O$_7$-like superconducting materials
High temperature superconductivity has been found in Fe, Ni, and Cu compounds, but not Co, where the Ni compounds include the recently found bilayer nickelate La$_3$Ni$_2$O$_7$ under high pressure. Here we theoretically predict several Co-based La$_3$Ni$_2$O$_7$-like high-temperature superconducting materials. With electron doping to high-pressure bilayer cobaltate La$_3$Co$_2$O$_7$, we find that LaTh$_2$Co$_2$O$_7$, La$_3$Ni$_2$O$_5$Cl$_2$, and La$_3$Ni$_2$O$_5$Br$_2$ may show similar crystal …

FRaN-X: FRaming and Narratives-eXplorer
We present FRaN-X, a Framing and Narratives Explorer that automatically detects entity mentions and classifies their narrative roles directly from raw text. FRaN-X comprises a two-stage system that combines sequence labeling with fine-grained role classification to reveal how entities are portrayed as protagonists, antagonists, or innocents, using a unique taxonomy of 22 fine-grained roles nested under these three main categories. The system supports five languages (Bulgarian, English, Hindi, R…

$\textit{Ab initio}$ Exact Calculation of Strongly-Correlated Nucleonic Matter
Dense nucleonic matter is of vital importance for understanding compact stars and inferring the transition into deconfined quark phase. We present the $\textit{ab initio}$ exact calculations of infinite nucleonic matter with the state-of-the-art full configuration-interaction quantum Monte Carlo (FCIQMC) method, enabling us to rigorously benchmark many-body methods and assess the degree to which the nucleonic matter is strongly correlated. This method has been numerically testified to exact dia…

Role of two-body dissipation on the mean-field dynamics validity
The role of two-body dissipation in nuclear reactions at energies of several times Coulomb barrier remains unclear but is crucial for understanding the mechanisms of deep-inelastic reactions. In this letter, we report a systematic analysis of two-body dissipation effects on the validity of mean-field dynamics, enabled by the TDHF-QRx approach, which incorporates the collision term via the relaxation-time approximation rather than full collision calculations. For deep-inelastic reactions, the co…
