Pedro H Pereira et al.
We report on a microscopic theory of quantum friction. Our approach investigates the interplay between the dispersive response and the relative center-of-mass motion of two ground-state atoms. This coupling yields a quantum force, which can...
Search for Signatures of Dark Matter Annihilation in the Galactic Center with HAWC [0.03%]
利用HAWC搜索银心暗物质湮灭迹象

R Alfaro et al.
We conduct an indirect dark matter (DM) search in the vicinity of the Galactic Center, focusing on a square region within ±9° in Galactic longitude and latutide, using 2865 days of data (∼8 yr) from the High-Altitude Water Cherenkov (HAW...
Subexponential Decay of Local Correlations from Diffusion-Limited Dephasing [0.03%]

Chaotic quantum systems at finite entropy density are expected to act as their own heat baths, rapidly dephasing local quantum superpositions. We argue that in fact this dephasing is generically subexponential in one-dimensional systems wit...
Quench Instabilities of a Strongly Interacting Quantum Gas in an Optical Cavity [0.03%]

Recent quench experiments on ultracold atoms in optical cavities provide a clean platform for studying how long-range interactions in atomic media structure their nonequilibrium dynamics. Motivated by these experiments, we provide a theoret...
Fingerprints of Preformed Pairs in Two-Electron Angle-Resolved Photoemission Spectroscopy [0.03%]

We use variational exact diagonalization (VED) to calculate the two-electron removal spectral weight for the Hubbard-Holstein model, starting from the ground state with two electrons on a one-dimensional chain. We argue that this spectral w...
Spinless and Spinful Charge Excitations in Moiré Fractional Chern Insulators [0.03%]
无自旋和有自旋的电荷激发在莫尔分数陈绝缘体中的研究

Miguel Gonçalves et al.
Fractionally charged elementary excitations, the quasielectron and quasihole, are hallmarks of the fractional Chern insulator. We observe that spontaneous spin polarization in twisted MoTe_{2} leads to multiple species of low-energy quasipa...

Storage and retrieval refer to the task of encoding an unknown quantum channel Λ into a quantum state, known as the program state, such that the channel can later be retrieved. There are two strategies for this task: classical and quantum ...

We present a fully Bayesian, data-driven framework for identifying quasinormal modes in high-accuracy Cauchy characteristic evolution gravitational waveforms. Applying this to a public catalog, we identify quasinormal mode overtones, retrog...

A background-free intensity autocorrelation measurement for 10-keV femtosecond x-ray pulses is demonstrated using x-ray second harmonic generation. The narrow phase-matching condition of x-ray second harmonic generation allows for the selec...
Optimally Tensile Strained La_{3}Ni_{2}O_{7} Films as Candidate High-Temperature Superconductors on Designer Substrates Ba_{1-x}Sr_{x}O and SrO-Terminated SrTiO_{3} [0.03%]
在设计基板Ba_{1-x}Sr_{x}O和SrO终止的SrTiO_{3}上具有最佳拉伸应变的La_{3}Ni_{2}O_{7}薄膜作为高温超导体候选者

Liangliang Liu et al.
High-temperature superconductivity in La_{3}Ni_{2}O_{7}-derived films with critical temperatures (T_{c}) of 40-50 K has so far been realized only under substrate-induced compressive strain. Here we use first-principles calculations to predi...
