The Fermi-Hubbard model is a key concept in condensed matter physics and provides
crucial insights into electronic and magnetic properties of materials. Yet, the intricate nature …

The nature of the behavior of an isolated many-body quantum system periodically driven in
time has been an open question since the beginning of quantum mechanics. After an initial …

We analyze in detail the heating of bosonic atoms in an optical lattice due to incoherent
scattering of light from the lasers forming the lattice. Because atoms scattered into higher …

The Bose‐Hubbard model is the simplest model of interacting bosons on a lattice. It has
recently been the focus of much attention due to the realization of this model with cold atoms …

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 demonstrate that arbitrary time evolutions of many-body quantum systems can be
reversed even in cases when only part of the Hamiltonian can be controlled. The reversed …

In this work, we use inelastic scattering of light to study the response of inhomogeneous Mott-
insulator gases to external excitations. The experimental setup and procedure to probe the …

We consider two species of hard-core bosons with density-dependent hopping in a one-
dimensional optical lattice, for which we propose experimental realizations using time …

We study the real-time dynamics of the Bose-Hubbard model in the presence of time-
dependent hopping, allowing for a finite-temperature initial state. We use the Schwinger …

We numerically study a particle in a box with moving walls. In the case where the walls are
oscillating sinusoidally with a small amplitude, we show that states up to the fourth state can …
