Driven Brownian transport through arrays of symmetric obstacles
P. K. Ghosh, P. Hanggi, F. Marchesoni +4
We numerically investigate the transport of a suspended overdamped Brownian particle which is driven through a two-dimensional rectangular array of circular obstacles with finite r…
Fluctuation, Dissipation and the Arrow of Time
Michele Campisi, Peter Hänggi
The recent development of the theory of fluctuation relations has led to new insights into the ever-lasting question of how irreversible behavior emerges from time-reversal symmetr…
Entropic Splitter for Particle Separation
D. Reguera, A. Luque, P. S. Burada +3
We present a particle separation mechanism which induces motion of particles of different sizes in opposite directions. The mechanism is based on the combined action of a driving f…
Biased Brownian motion in extreme corrugated tubes
Steffen Martens, Gerhard Schmid, Lutz Schimansky-Geier +1
Biased Brownian motion of point-size particles in a three-dimensional tube with smoothly varying cross-section is investigated. In the fashion of our recent work [Martens et al., P…
Phononics: Manipulating heat flow with electronic analogs and beyond
Nianbei Li, Jie Ren, Lei Wang +3
The form of energy termed heat that typically derives from lattice vibrations, i.e. the phonons, is usually considered as waste energy and, moreover, deleterious to information pro…
Distance between quantum states in presence of initial qubit-environment correlations: a comparative study
Jerzy Dajka, Jerzy Łuczka, Peter Hänggi
The time evolution of the trace distance between two states of an open quantum system may increase due to initial system-environment correlations, thus exhibiting a breakdown of di…
