Comment on "Coherent Ratchets in Driven Bose-Einstein Condensates"
G. Benenti, G. Casati, S. Denisov +4
C. E. Creffield and F. Sols (Phys. Rev. Lett. 103, 200601 (2009)) recently reported finite, directed time-averaged ratchet current, for a noninteracting quantum particle in a perio…
Markovian embedding of non-Markovian superdiffusion
Peter Siegle, Igor Goychuk, Peter Talkner +1
We consider different Markovian embedding schemes of non-Markovian stochastic processes that are described by generalized Langevin equations (GLE) and obey thermal detailed balance…
Molecular wires acting as quantum heat ratchets
Fei Zhan, Nianbei Li, Sigmund Kohler +1
We explore heat transfer in molecular junctions between two leads in the absence of a finite net thermal bias. The application of an unbiased, time-periodic temperature modulation…
Negative Mobility induced by Colored Thermal Fluctuations
M. Kostur, J. Luczka, P. Hanggi
Anomalous transport of non-Markovian, thermal Brownian particle dynamics in spatially-periodic symmetric systems that is driven by time-periodic symmetric driving and constant bias…
Many-Body Coherent Destruction of Tunneling
Jiangbin Gong, Luis Morales-Molina, Peter Hanggi
A new route to coherent destruction of tunneling is established by considering a monochromatic fast modulation of the self-interaction strength of a many-boson system. The modulati…
Double Entropic Stochastic Resonance
P. S. Burada, G. Schmid, D. Reguera +2
We demonstrate the appearance of a purely entropic stochastic resonance (ESR) occurring in a geometrically confined system, where the irregular boundaries cause entropic barriers.…
