Transport phenomena in spatially periodic systems far from thermal equilibrium are
considered. The main emphasis is put on directed transport in so-called Brownian motors (ratchets), …

We demonstrate the equilibration of isolated macroscopic quantum systems, prepared in
nonequilibrium mixed states with a significant population of many energy levels, and observed …

We investigate quantum Brownian motion in adiabatically rocked ratchet systems. Above a
crossover temperature T c tunneling events are rare, yet they already substantially enhance …

The present paper analyzes the self-generated explanations (from talk-aloud protocols) that
“Good” and “Poor” students produce while studying worked-out examples of mechanics …

For quantum systems that are weakly coupled to a much'bigger'environment, thermalization
of possibly far from equilibrium initial ensembles is demonstrated: for sufficiently large times, …

Massive open online courses (MOOCs) have exploded onto the scene, promising to satisfy
a worldwide thirst for a high-quality, personalized, and free education. This article explores …

An exact analytical expression for the effective diffusion coefficient of an overdamped
Brownian particle in a tilted periodic potential is derived for arbitrary potentials and arbitrary …

The effective diffusion coefficient for the overdamped Brownian motion in a tilted periodic
potential is calculated in closed analytical form. Universality classes and scaling properties for …

For a macroscopic, isolated quantum system in an unknown pure state, the expectation
value of any given observable is shown to hardly deviate from the ensemble average with …

A detailed introduction to directed transport in Brownian motors occurring in spatially periodic
systems far from equilibrium is presented. We elucidate the prominent physical concepts …
