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…
Effects of correlated noise on the excitation of robust breathers in an ac-driven, lossy sine-Gordon system
Giovanni Di Fresco, Duilio De Santis, Claudio Guarcello +3
Thermal noise and harmonic forcing have recently been shown to cooperatively excite sine-Gordon breathers robust to dissipation. Such a phenomenon has been found assuming a Gaussia…
Comment on "Non-reciprocal topological solitons in active metamaterials"
Duilio De Santis, Bernardo Spagnolo, Angelo Carollo +2
In the recent work "Non-reciprocal topological solitons in active metamaterials" (see arXiv:2312.03544v1), for an analytical understanding of the system under consideration, the au…
Quantum optics with giant atoms in a structured photonic bath
L. Leonforte, X. Sun, D. Valenti +4
We present a general framework to tackle quantum optics problems with giant atoms, i.e. quantum emitters each coupled {\it non-locally} to a structured photonic bath (typically a l…
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…
