Nonreciprocal and Long-Range Three-Body Interactions in Bose-Einstein Condensates Induced by Optical Feedback [0.03%]
光学反馈诱导的玻色-爱因斯坦凝聚中的非互易长程三体相互作用
Yi-Qing Zhang,Liang-Jun He,Han Pu et al.
Yi-Qing Zhang et al.
We propose generating atom-atom three-body interactions in quantum gases by placing a quasi-two-dimensional Bose-Einstein condensate in front of two reflecting mirrors and illuminating it with dichromatic laser beams. These pumping fields t...
Boosting Work Extraction in Quantum Batteries via Continuous Environment Monitoring [0.03%]

Gabriele Cenedese et al.
During the charging process, interactions between a quantum battery and its charger generally generate quantum correlations, which may reduce the amount of work extractable from the battery alone. We show that, by coupling the system with a...
Turbulent Nature of the Quasicontinuous Exhaust Regime for Fusion Plasmas [0.03%]
聚变等离子体准连续排气模式的湍流性质

We demonstrate a turbulence mechanism that reconciles high plasma confinement with efficient heat exhaust-a central challenge for fusion energy. Global two-fluid turbulence simulations of the reactor-relevant quasicontinuous exhaust regime ...

We calculate the bound and scattering properties of a system of two neutral atoms and an ion near an ion-atom Feshbach resonance. Our results indicate that long-range ion-atom interactions lead to significant deviations from universal behav...
Fermi-Surface-Sheet Dependent Electron-Phonon Coupling in a Borocarbide Superconductor YNi_{2}B_{2}C [0.03%]

We performed de Haas-van Alphen (dHvA) oscillation measurements and band-structure calculations for YNi_{2}B_{2}C. Our improved band structure successfully explained the origins of the large dHvA frequencies β and ζ, which were inexplicab...

Experiments show that the Weyl semimetal PtBi_{2} hosts unconventional superconductivity in its topological surface states. Hence, the material is a candidate for intrinsic topological superconductivity. Measurements indicate nodal gaps in ...

We study the full distribution of the zero-temperature Hall conductivity in a lattice model of the integer quantum Hall effect across disorder realizations. Near the plateau transition, the distributions develop heavy power-law tails with e...

Weizhe Zhang et al.
Hyperbolic polaritons exhibit nonclosed hyperbolic isofrequency contours and hold great promise for integrated photonics due to their ultralarge momentum and directional propagation characteristics. However, their direct far-field observati...
Unconventional Unidirectional Spin Hall Magnetoresistance in Epitaxial IrMn/FeNi Bilayer [0.03%]

Haiming Xu et al.
Unidirectional spin Hall magnetoresistance (USMR), arising from the interaction between nonequilibrium spin accumulation and magnetization, has been proposed as a simple two-terminal method for electrically detecting magnetic states in heav...
Higher Josephson Harmonics in a Tunable Double-Junction Transmon Qubit [0.03%]
