Time-periodic (Floquet) driving is a powerful way to control the dynamics of complex
systems, which can be used to induce a plethora of new physical phenomena. However …

Statistical mechanics provides a framework for describing the physics of large, complex
many-body systems using only a few macroscopic parameters to determine the state of the …

Partial transport barriers in the chaotic sea of Hamiltonian systems influence classical
transport, as they allow for a small flux between chaotic phase-space regions only. We find …

Floquet modulation has been widely used in optical lattices for coherent control of quantum
gases, in particular for synthesizing artificial gauge fields and simulating topological matters …

Quantum directed transport can be realized in noninteracting, deterministic, chaotic systems
by appropriately breaking the spatiotemporal symmetries in the potential. In this work, the …

We demonstrate that quantum dynamical localization in the Arnold web of higher-
dimensional Hamiltonian systems is destroyed by an intrinsic classical drift. Thus quantum …

A particle with finite initial velocity in a disordered potential comes back and on average
stops at the original location. This phenomenon, dubbed the “quantum boomerang …

Driven many-body systems typically experience heating due to the lack of energy
conservation. Heating may be suppressed for time-periodic drives, but little is known for less …

One major objective of controlling classical chaotic dynamical systems is exploiting the
system's extreme sensitivity to initial conditions in order to arrive at a predetermined target …

We investigate the quantum irreversibility and quantum diffusion in a non-Hermitian kicked
rotor model for which the kicking strength is complex. Our results show that the exponential …
