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…

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-differ…

Stochastic resonance in a metal-oxide memristive device
A. N. Mikhaylov, D. V. Guseinov, A. I. Belov +13
The stochastic resonance phenomenon has been studied experimentally and theoretically for a state-of-art metal-oxide memristive device based on yttria-stabilized zirconium dioxide…
