Dissipative response of driven bead-spring-dashpot chains
The work dissipated in pulling a polymer chain with internal friction is numerically calculated by considering a sequence of $N$ bead-spring-dashpots tethered at one end and being pulled at the other using a harmonic trap via linear and symmetric protocols. The variation of the dissipation with the chain length, pulling trap stiffness, and the internal friction parameter are examined in detail for both the protocols. In the limit of high trap stiffness: (i) the dissipation $decreases$ with $N$ …

Engineering Cryogenic FETs: Addressing SCEs and Impact of Interface Traps Down to 2 K Temperature
This paper presents a comprehensive design and benchmarking of cryogenic bulk-FET using a calibrated TCAD model integrating 2-D electrostatics and interface trap effects across temperatures from T = 2 K to 300 K. For a 28-nm node FET, transport appears predominately ballistic at T = 2 K, shifting toward quasi-ballistic transport with increasing temperature. Short-channel effects (SCEs) dominate cryogenic benefits at Lg = 25 nm for T < 25 K, as evidenced by a modest improvement in the minimum su…

Trap-to-trap free falls with an optically levitated nanoparticle
We perform free-fall experiments with a charge-neutral, optically levitated nanoparticle. This is achieved using an optical tweezer that can be rapidly toggled on and off and vertically displaced, enabling the particle to be released and recaptured after each free fall. The particle is insensitive to electric fields due to its charge neutrality and, during free evolution, is not subject to photon recoil heating. We achieve free-fall durations of up to 0.25 ms and observe a nearly two hundred-fo…

- Suppose you don't want to catch a mouse but just want to break someone's finger. Is there something you can use for that?
- Yes! An ordinary mouse trap, the kind you break a mouse's neck with, can also be used to break someone's finger! Thanks for asking.

Tension-Induced Soft Stress and Viscoelastic Bending in Liquid Crystal Elastomers for Enhanced Energy Dissipation

Tension-Induced Soft Stress and Viscoelastic Bending in Liquid Crystal Elastomers for Enhanced Energy Dissipation
Architected materials that harness elastic snap-through buckling can trap energy reversibly. Liquid crystal elastomers (LCEs) exhibit excellent dissipation capabilities due to polymer network viscoelasticity and rate-dependent soft stress behavior associated with mesogen rotation. Incorporating LCEs into buckling lattice structures enhances energy absorption; however, conventional design cannot take advantage of the dissipation mechanism associated with mesogen rotation because buckling occurs …

Finished “Trap Line”, a short story by Timothy Zahn.
Interstellar travel is possible by transporting your consciousness to a cloned body already at the destination. But when an engineer is sent to repair a spacecraft’s communications array, he is instead entrapped in his disembodied state by aliens. The only way out, say fellow entrapped aliens, is death.
Enjoyable, but somewhat lacking, like a junk food version of Andy Weir.

Quantum Kramers-Henneberger Transformation
The classical Kramers-Henneberger transformation connects, via a series of unitary transformations, the dynamics of a quantum particle of mass $m$ located in a trap at position $α(t)$, with the dynamics of a charge $e$ moving in an electric field $e{\cal{E}}(t)=-m\ddotα(t)$ within the dipole approximation. In this paper, we extend the classical Kramers-Henneberger transformation to the quantum electrodynamic and quantum optical realm, by explicitly treating the trap location quantum mechanica…

Using optical tweezers to simultaneously trap, charge and measure the charge of a microparticle in air
Optical tweezers are widely used as a highly sensitive tool to measure forces on micron-scale particles. One such application is the measurement of the electric charge of a particle, which can be done with high precision in liquids, air, or vacuum. We experimentally investigate how the trapping laser itself can electrically charge such a particle, in our case a $\sim 1\,\mathrm{μm\;SiO_2}$ sphere in air. We model the charging mechanism as a two-photon process which reproduces the experimental …

Experimental search for electric dipole moments of light radioactive nuclei
We discuss a search for the electric dipole moment (EDM) of a light beta-radioactive ion using a compact ion trap by adapting the "frozen-spin" method. The measurement will be done on ions stripped of their valence electrons, thereby bypassing the significant Schiff screening that hinders the application of successful contemporary EDM searches using heavy neutral atoms and molecules to light nuclei. We identified $^8$Li as the most promising candidate for a proof-of-concept EDM search and we es…

Optimal dynamical stabilization
Stability is a fundamental concept that refers to a system's ability to return close to its original state after disturbances. The minimal conditions for stability when system parameters vary in time, though common in physics, have been largely overlooked. Here, we study the minimal amount of periodic stiffness a linear mass-spring system requires to remain stable and apply our findings to optimally trap the upside-down state of a compass in a time-varying magnetic field. We show that the abili…

Alkali doping of Zn$_{\rm x}$Mg$_{\rm 1-x}$O alloys for $p$-type conductivity
Nearly all ultrawide-bandgap oxides are affected by hole localization that limits $p$-type conductivity and thus potential applications for these materials. Highly localized holes, also known as hole polarons, trap in the vicinity of acceptor dopants, giving rise to large ionization energies and severely constraining free hole concentrations. Though this hole-trapping behavior affects wurtzite zinc oxide, rocksalt zinc oxide was recently found to be resistant to the formation of hole polarons. …

Experimental demonstration of high-fidelity logical magic states from code switching
Preparation of high-fidelity logical magic states has remained as a necessary but daunting step towards building a large-scale fault-tolerant quantum computer. One approach is to fault-tolerantly prepare a magic state in one code and then switch to another, a method known as code switching. We experimentally demonstrate this protocol on an ion-trap quantum processor, yielding a logical magic state encoded in an error-correcting code with state-of-the-art logical fidelity. Our experiment is base…

Energy Dynamics of a Nonequilibrium Unitary Fermi Gas
We investigate the energy dynamics of a unitary Fermi gas driven away from equilibrium. The energy is injected into the system by periodically modulating the trapping potential of a spherical unitary Fermi gas, and due to the existence of SO(2,1) symmetry, the breathing mode is excited without dissipation. Through the long-lived breathing oscillation, we precisely measure the energy evolution of the nonequilibrium system during the trap modulation. We find the trapping potential and internal en…

Long-time storage of a decoherence-free subspace logical qubit in a dual-type quantum memory
A quantum memory is an essential element for quantum computation, quantum network and quantum metrology. Previously, a single-qubit quantum memory with a coherence time of about an hour has been realized in a dual-species setup where a coolant ion provides sympathetic cooling for a memory ion of different species. However, the frequent random position hopping between the ions in the room-temperature trap limits the technique there only applicable to single-qubit storage. Here we report a multi-…
