Noise-Assisted Metastability: From Lévy Flights to Memristors, Quantum Escape, and Josephson-based Axion Searches
Claudio Guarcello, Alexander A. Dubkov, Davide Valenti +1
Many-body and complex systems, both classical and quantum, often exhibit slow, nonlinear relaxation toward stationary states due to the presence of metastable configurations and en…
Kinetic description of one-dimensional stochastic dynamics with small inertia
Denis S. Goldobin, Lyudmila S. Klimenko, Irina V. Tyulkina +2
We study single-variable approaches for describing stochastic dynamics with small inertia. The basic models we deal with describe passive Brownian particles and phase elements (pha…
Enhancement of stability of metastable states in the presence of Lévy noise
A. A. Dubkov, C. Guarcello, B. Spagnolo
The barrier-crossing event for superdiffusion characterized by symmetric Lévy flights is analyzed. Starting from the fractional Fokker-Planck equation, we derive an integro-differe…
Game-driven random walks: Survival time statistics
M. I. Krivonosov, S. N. Tikhomirov, S. Denisov
Random walks are powerful tools to analyze spatial-temporal patterns produced by living organisms ranging from cells to humans. At the same time, it is evident that these patterns…
Four approaches for description of stochastic systems with small and finite inertia
Evelina V. Permyakova, Lyudmila S. Klimenko, Irina V. Tyulkina +1
We analyse four approaches to elimination of a fast variable, which are applicable to systems like passive Brownian particles: (i) moment formalism, (ii) corresponding cumulant for…
Random generators of Markovian evolution: A quantum-classical transition by superdecoherence
W. Tarnowski, I. Yusipov, T. Laptyeva +3
Continuous-time Markovian evolution appears to be manifestly different in classical and quantum worlds. We consider ensembles of random generators of -dimensional Markovian evol…
