The newly discovered family of nonmagnetic kagome metals AV_{3}Sb_{5} (A=K, Rb, or Cs) provides a unique platform for exploring the interplay between charge-density wave (CDW) order, superconductivity, nontrivial topology, and spontaneous t...
Wavenumber Lock-in in Buckled Elastic Structures: An Analogue to Parametric Instabilities [0.03%]
皱弹性结构中的波数锁频：参数不稳定的类比现象

H E Read et al.
Parametric instabilities are a known feature of periodically driven dynamic systems; at particular frequencies and amplitudes of the driving modulation, the system's quasiperiodic response undergoes a frequency lock-in, leading to a periodi...
Observation of Metal-Insulator and Spectral Phase Transitions in Aubry-André-Harper Models [0.03%]

Quan Lin et al.
Non-Hermitian extensions of the Aubry-André-Harper (AAH) model reveal a rich variety of phase transitions arising from the interplay of quasiperiodicity and nonhermiticity. Despite their theoretical significance, experimental explorations ...

Photoexcitation has been utilized to control quantum matter and to uncover metastable phases far from equilibrium. Among demonstrations to date, the most common is the photoinduced transition from correlated insulators to metallic states; h...

We theoretically investigate the role of spatial dimension and driving frequency in a nonequilibrium phase transition of a driven-dissipative interacting bosonic system. In this setting, spatial dimension is dictated by the shape of the ext...
Glauber-Theory Calculations of High-Energy Nuclear Scattering Observables Using Variational Monte Carlo Wave Functions [0.03%]

Experiments using intermediate- to high-energy radioactive nuclear beams present numerous findings. Extracting important properties of physical observables relies on a firm theoretical analysis. Though Glauber theory is believed to work wel...
Raman Optical Activity Induced by Ferroaxial Order in NiTiO_{3} [0.03%]
NiTiO₃中ferroaxial有序引起的拉曼光学活性

Gakuto Kusuno et al.
Raman optical activity (ROA), the dependence of Raman intensity on the circular polarization of incident and scattered light, has traditionally been observed in chiral molecules and magnetic materials, where inversion or time-reversal symme...
Lellouch-Lüscher Relation for Ultracold Few-Atom Systems under Confinement [0.03%]
受限条件下超冷少体原子系统的Lellouch-Lüscher关系式
Jing-Lun Li,Paul S Julienne,Johannes Hecker Denschlag et al.
Jing-Lun Li et al.
We derive an analog of the Lellouch-Lüscher (LL) relation for few-body bosonic systems, linking few-body scattering loss rates to the energies and widths of the corresponding harmonically trapped few-body states. Three-body numerical simul...

We investigate displacive short-range order in pyrochlore Y_{2}Nb_{2}O_{7}, which exhibits a nonmagnetic insulating state despite the presence of formally tetravalent Nb^{4+} (S=1/2) ions on the pyrochlore network. Synchrotron x-ray diffrac...

Temporal metamaterials, created by modulating the refractive index in time, offer powerful means of controlling wave propagation but still lack a systematic design methodology. Here, we develop an analytic inverse-design framework rooted in...
