Diffusion of Chiral Janus Particles in a Sinusoidal Channel
Xue Ao, Pulak Kumar Ghosh, Yunyun Li +3
We investigate the transport diffusivity of artificial microswimmers, a.k.a. Janus particles, moving in a sinusoidal channel in the absence of external biases. Their diffusion cons…
Josephson junction ratchet: effects of finite capacitances
Jakub Spiechowicz, Peter Hänggi, Jerzy Łuczka
We study transport in an asymmetric SQUID which is composed of a loop with three capacitively and resistively shunted Josephson junctions: two in series in one arm and the remainin…
Geometric quantum pumping in the presence of dissipation
Juzar Thingna, Peter Hänggi, Rosario Fazio +1
The charge transported when a quantum pump is adiabatically driven by time-dependent external forces in presence of dissipation is given by the line integral of a pumping field $\m…
