Open AccessSelf-Polarizing Microswimmers in Active Density Waves
An artificial microswimmer drifts in response to spatio-temporal modulations of an activating suspension medium. We consider two competing mechanisms capable of influencing its tactic response: angular fluctua...

Open AccessTransient anomalous diffusion in periodic systems: ergodicity, symmetry breaking and velocity relaxation
We study far from equilibrium transport of a periodically driven inertial Brownian particle moving in a periodic potential. As detected for a SQUID ratchet dynamics, the mean square deviation of the particle p...

Open AccessExperimental control of transport resonances in a coherent quantum rocking ratchet
The ratchet phenomenon is a means to get directed transport without net forces. Originally conceived to rectify stochastic motion and describe operational principles of biological motors, the ratchet effect ca...

Open AccessBoosting thermoelectric efficiency using time-dependent control
Thermoelectric efficiency is defined as the ratio of power delivered to the load of a device to the rate of heat flow from the source. Till date, it has been studied in presence of thermodynamic constraints se...
