Engineering Topological Phases with a Traveling‐Wave Spacetime Modulation
Laser &Photonics Reviews, EarlyView.Time‐varying systems have garnered considerable attention due to their unique potential in manipulating electromagnetic waves. Here, a novel class of topological spacetime crystals with a traveling‐wave modulation is introduced. By manipulating material anisotropy, one can engineer light angular momentum and non‐trivial topological phases characterized

Path-integral isomorphic Hamiltonian for including nuclear quantum effects in non-adiabatic dynamics [PDF]
, 2018 We describe a path-integral approach for including nuclear quantum effects in non-adiabatic chemical dynamics simulations. For a general physical system with multiple electronic energy levels, a corresponding isomorphic Hamiltonian is introduced such ...

Semiclassical approximations for Hamiltonians with operator-valued symbols
, 2012 We consider the semiclassical limit of quantum systems with a Hamiltonian given by the Weyl quantization of an operator valued symbol. Systems composed of slow and fast degrees of freedom are of this form.

Short‐Range Order and LixTM4−x Probability Maps for Disordered Rocksalt Cathodes
Small, EarlyView.Monte Carlo mapping with a simplified cluster description framework discloses the origin of Li4${\rm Li}_4$ deficiency and unfavorable short‐range order prevalent in most DRX materials. Statistical mechanical sampling indicates that ordering quantities in the disordered state do not necessarily represent a simple attenuation of their low‐temperature ...
