Lévy walks
V. Zaburdaev, S. Denisov, J. Klafter
Random walk is a fundamental concept with applications ranging from quantum physics to econometrics. Remarkably, one specific model of random walks appears to be ubiquitous across…
Infinite densities for Lévy walks
Adi Rebenshtok, Sergey Denisov, Peter Hanggi +1
Motion of particles in many systems exhibits a mixture between periods of random diffusive like events and ballistic like motion. In many cases, such systems exhibit strong anomalo…
Levy walks with velocity fluctuations
S. Denisov, V. Zaburdaev, P. Hanggi
The standard Levy walk is performed by a particle that moves ballistically between randomly occurring collisions, when the intercollision time is a random variable governed by a po…
Quantum thermal equilibration from equipartition
A. V. Ponomarev, S. Denisov, J. Gemmer +1
The problem of mutual equilibration between two finite, identical quantum systems, A and B, prepared initially at different temperatures is elucidated. We show that the process of…
Thermal equilibration between two quantum systems
Alexey V. Ponomarev, Sergey Denisov, Peter Hänggi
Two identical finite quantum systems prepared initially at different temperatures, isolated from the environment, and subsequently brought into contact are demonstrated to relax to…
Ratchet transport with subdiffusion
S. Denisov
We introduce a model which incorporate the subdiffusive dynamics and the ratchet effect. Using a subordination ideology, we show that the resulting directed transport is sublinear,…
