Space-time velocity correlation function for random walks
V. Zaburdaev, S. Denisov, P. Hanggi
Space-time correlation functions constitute a useful instrument from the research toolkit of continuous-media and many-body physics. We adopt here this concept for single-particle…
Mapping the Arnold web with a GPU-supercomputer
A. Seibert, S. Denisov, A. V. Ponomarev +1
The Arnold diffusion constitutes a dynamical phenomenon which may occur in the phase space of a non-integrable Hamiltonian system whenever the number of the system degrees of freed…
Quantum ratchet transport with minimal dispersion rate
Fei Zhan, S. Denisov, A. V. Ponomarev +1
We analyze the performance of quantum ratchets by considering the dynamics of an initially localized wave packet loaded into a flashing periodic potential. The directed center-of-m…
Perturbation spreading in many-particle systems: a random walk approach
V. Zaburdaev, S. Denisov, P. Hanggi
The propagation of an initially localized perturbation via an interacting many-particle Hamiltonian dynamics is investigated. We argue that the propagation of the perturbation can…
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…
Levy distribution in many-particle quantum systems
A. V. Ponomarev, S. Denisov, P. Hanggi
Levy distribution, previously used to describe complex behavior of classical systems, is shown to characterize that of quantum many-body systems. Using two complimentary approaches…
