Transport properties of particles and waves in spatially periodic structures that are driven by
external time-dependent forces manifestly depend on the space–time symmetries of the …

Valence and conduction bands in nodal loop semimetals (NLSMs) touch along closed loops
in momentum space. If such loops can proliferate and link intricately, NLSMs become exotic …

Floquet topological matter has emerged as one exciting platform to explore rich physics and
game-changing applications of topological phases. As one remarkable and recently …

We investigate the spectral properties and dynamical features of a time-periodic PT-
symmetric Hamiltonian on a one-dimensional tight-binding lattice. It is shown that a high …

We present a simple, experimentally realizable method to make coherent three-body
interactions dominate the physics of an ultracold lattice gas. Our scheme employs either …

Several recent studies have investigated the dynamics of cold atoms in optical lattices
subject to ac forcing; the theoretically predicted renormalization of the tunneling amplitudes …

A time-dependent optical lattice with staggered particle current in the tight-binding regime
was considered that can be described by a time-independent effective lattice model with an …

We study a gas of interacting ultracold bosons held in a parabolic trap in the presence of an
optical lattice potential. Treating the system as a discretized Gross-Pitaevskii model, we …

We examine the dynamics of ultracold atoms held in optical-lattice potentials. By controlling
the switching of a periodic driving potential we show how a phase-induced renormalization …

We study the nonequilibrium dynamics of cold atoms held in an optical lattice subjected to a
periodic driving potential. The expansion of an initially confined atom cloud occurs in two …
