Topological photonics is a new and rapidly growing field that deals with topological phases
and topological insulators for light. Recently, the scope of these systems was expanded …

Fidelity serves as a benchmark for the reliability in quantum information processes, and has
recently attracted much interest as a measure of the susceptibility of dynamics to …

We consider disordered many-body systems with periodic time-dependent Hamiltonians in
one spatial dimension. By studying the properties of the Floquet eigenstates, we identify two …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

It was proposed recently that the out-of-time-ordered four-point correlator (OTOC) may serve
as a useful characteristic of quantum-chaotic behavior, because, in the semiclassical limit …

The distinction between level clustering and level repulsion is one of the quantum
analogues of the classical distinction between globally regular and predominantly chaotic …

We study dynamics of isolated quantum many-body systems whose Hamiltonian is switched
between two different operators periodically in time. The eigenvalue problem of the …

The phenomenon of tunneling is investigated for a symmetric double-well potential
perturbed by a monochromatic driving force. The analysis is based on a numerical treatment …

We investigate the quantum-chaotic properties of the Dicke Hamiltonian; a quantum-optical
model that describes a single-mode bosonic field interacting with an ensemble of N two …

We consider the Dicke Hamiltonian, a simple quantum-optical model which exhibits a zero-
temperature quantum phase transition. We present numerical results demonstrating that at …
