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…
Noise-induced, ac-stabilized sine-Gordon breathers: Emergence and statistics
Duilio De Santis, Claudio Guarcello, Bernardo Spagnolo +2
Noisy and ac forcing can cooperatively lead to the emergence of sine-Gordon breathers robust to dissipation. This phenomenon is studied, for both Neumann and periodic boundary cond…
Heat-transfer fingerprint of Josephson breathers
Duilio De Santis, Bernardo Spagnolo, Angelo Carollo +2
A sine-Gordon breather enhances the heat transfer in a thermally biased long Josephson junction. This solitonic channel allows for the tailoring of the local temperature throughout…
ac-locking of thermally-induced sine-Gordon breathers
Duilio De Santis, Claudio Guarcello, Bernardo Spagnolo +2
A complete framework for exciting and detecting thermally-induced, stabilized sine-Gordon breathers in ac-driven long Josephson junctions is developed. The formation of long-time s…
Supratransmission-induced travelling breathers in long Josephson junctions
Duilio De Santis, Claudio Guarcello, Bernardo Spagnolo +2
The emergence of travelling sine-Gordon breathers due to the nonlinear supratransmission effect is theoretically studied in a long Josephson junction driven by suitable magnetic pu…
Generation of travelling sine-Gordon breathers in noisy long Josephson junctions
Duilio De Santis, Claudio Guarcello, Bernardo Spagnolo +2
The generation of travelling sine-Gordon breathers is achieved through the nonlinear supratransmission effect in a magnetically driven long Josephson junction, in the presence of l…
Voltage drop across Josephson junctions for Lévy noise detection
Claudio Guarcello, Giovanni Filatrella, Bernardo Spagnolo +2
We propose to characterize Lévy-distributed stochastic fluctuations through the measurement of the average voltage drop across a current-biased Josephson junction. We show that the…
On critical properties of Berry curvature in Kitaev honeycomb model
Francesco Bascone, Luca Leonforte, Davide Valenti +2
We analyse the Kitaev honeycomb model, by means of the Berry curvature with respect to Hamiltonian parameters. We concentrate on the ground-state vortex-free sector, which allows u…
Finite temperature geometric properties of the Kitaev honeycomb model
Francesco Bascone, Luca Leonforte, Bernardo Spagnolo +2
We study finite temperature topological phase transitions of the Kitaev's spin honeycomb model in the vortex-free sector with the use of the recently introduced mean Uhlmann curvat…
Josephson-based threshold detector for Lévy distributed fluctuations
Claudio Guarcello, Davide Valenti, Bernardo Spagnolo +2
We propose a threshold detector for Lévy distributed fluctuations based on a Josephson junction. The Lévy noise current added to a linearly ramped bias current results in clear cha…
Anomalous transport effects on switching currents of graphene-based Josephson junctions
Claudio Guarcello, Davide Valenti, Bernardo Spagnolo +2
We explore the effect of noise on the ballistic graphene-based small Josephson junctions in the framework of the resistively and capacitively shunted model. We use the non-sinusoid…
Quantum dissipative dynamics of a bistable system in the sub-Ohmic to super-Ohmic regime
Luca Magazzù, Angelo Carollo, Bernardo Spagnolo +1
We investigate the quantum dynamics of a multilevel bistable system coupled to a bosonic heat bath beyond the perturbative regime. We consider different spectral densities of the b…
Enhancement of electron spin lifetime in GaAs crystals: the benefits of dichotomous noise
Stefano Spezia, Dominique Persano Adorno, Nicola Pizzolato +1
The electron spin relaxation process in n-type GaAs crystals driven by a fluctuating electric field is investigated. Two different sources of fluctuations are considered: (i) a sym…
Design of a Lambda system for population transfer in superconducting nanocircuits
G. Falci, A. La Cognata, M. Berritta +3
The implementation of a Lambda scheme in superconducting artificial atoms could allow detec- tion of stimulated Raman adiabatic passage (STIRAP) and other quantum manipulations in…
