Ratchet effects can arise for single or collectively interacting Brownian particles on an
asymmetric substrate when a net dc transport is produced by an externally applied ac …

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 …

Written by two of the world's leading researchers in the field, this is a systematic introduction
to the fundamental principles of coherent control, and to the underlying physics and …

We demonstrated experimentally that the momentum distribution of cold atoms in dissipative
optical lattices is a Tsallis distribution. The parameters of the distribution can be continuously …

Brownian motion is a manifestation of the fluctuation− dissipation theorem of statistical
mechanics. It regulates systems in physics, biology, chemistry, and finance. We use …

We study the quantum version of a tilting and flashing Hamiltonian ratchet, consisting of a
periodic potential and a time-periodic driving field. The system dynamics is governed by a …

We analyze the atomic dynamics in an ac driven periodic optical potential which is
symmetric in both time and space. We experimentally demonstrate that in the presence of …

We demonstrate that a cycle of three holographic optical trap** patterns can implement a
thermal ratchet for diffusing colloidal spheres and that the ratchet-driven transport displays …

Measurements of hydrodynamic instability growth for a high-density carbon ablator for
indirectly driven inertial confinement fusion implosions on the National Ignition Facility are …

Using computer simulations, we study a two-dimensional system of sterically interacting self-
mobile run-and-tumble disk-shaped particles with an underlying periodic quasi-one …
