Transport of Forced Quantum Motors in the Strong Friction Limit
Lukasz Machura, Jerzy Luczka, Peter Talkner +1
The directed transport of an overdamped Brownian motor moving in a spatially periodic potential that lacks reflection symmetry (i.e. a ratchet potential) is studied when driven by…
Nonadiabatic electron heat pump
Miguel Rey, Michael Strass, Sigmund Kohler +2
We investigate a mechanism for extracting heat from metallic conductors based on the energy-selective transmission of electrons through a spatially asymmetric resonant structure su…
Relative entropy, Haar measures and relativistic canonical velocity distributions
Jörn Dunkel, Peter Talkner, Peter Hänggi
The thermodynamic maximum principle for the Boltzmann-Gibbs-Shannon (BGS) entropy is reconsidered by combining elements from group and measure theory. Our analysis starts by noting…
Absolute negative mobility induced by thermal equilibrium fluctuations
L. Machura, M. Kostur, P. Talkner +2
A novel transport phenomenon is identified that is induced by inertial Brownian particles which move in simple one-dimensional, symmetric periodic potentials under the influence of…
Gauging a quantum heat bath with dissipative Landau-Zener transitions
Martijn Wubs, Keiji Saito, Sigmund Kohler +2
We calculate the exact Landau-Zener transitions probabilities for a qubit with arbitrary linear coupling to a bath at zero temperature. The final quantum state exhibits a peculiar…
