First passage and first hitting times of Lévy flights and Lévy walks

VV Palyulin, G Blackburn, MA Lomholt… - New Journal of …, 2019 - iopscience.iop.org
For both Lévy flight and Lévy walk search processes we analyse the full distribution of first-
passage and first-hitting (or first-arrival) times. These are, respectively, the times when the …

Josephson-based threshold detector for Lévy-distributed current fluctuations

C Guarcello, D Valenti, B Spagnolo, V Pierro… - Physical Review …, 2019 - APS
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 …

Anomalous transport effects on switching currents of graphene-based Josephson junctions

C Guarcello, D Valenti, B Spagnolo, V Pierro… - …, 2017 - iopscience.iop.org
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-sinusoidal …

Nonlinear relaxation phenomena in metastable condensed matter systems

B Spagnolo, C Guarcello, L Magazzù, A Carollo… - Entropy, 2016 - mdpi.com
Nonlinear relaxation phenomena in three different systems of condensed matter are
investigated.(i) First, the phase dynamics in Josephson junctions is analyzed. Specifically, a …

Effects of Lévy noise on the dynamics of sine-Gordon solitons in long Josephson junctions

C Guarcello, D Valenti, A Carollo… - Journal of Statistical …, 2016 - iopscience.iop.org
We numerically investigate the generation of solitons in current-biased long Josephson
junctions in relation to the superconducting lifetime and the voltage drop across the device …

Lévy flights versus Lévy walks in bounded domains

B Dybiec, E Gudowska-Nowak, E Barkai, AA Dubkov - Physical Review E, 2017 - APS
Lévy flights and Lévy walks serve as two paradigms of random walks resembling common
features but also bearing fundamental differences. One of the main dissimilarities is the …

Stepping molecular motor amid Lévy white noise

B Lisowski, D Valenti, B Spagnolo, M Bier… - Physical Review E, 2015 - APS
We consider a model of a stepping molecular motor consisting of two connected heads.
Directional motion of the stepper takes place along a one-dimensional track. Each head is …

Dynamics of two competing species in the presence of Lévy noise sources

A La Cognata, D Valenti, AA Dubkov… - Physical Review E …, 2010 - APS
We consider a Lotka-Volterra system of two competing species subject to multiplicative α-
stable Lévy noise. The interaction parameter between the species is a random process …
