Faceted patterns and anomalous surface roughening driven by long-range temporally correlated noise
(American Physical Society, 2019-06)
We investigate Kardar-Parisi-Zhang (KPZ) surface growth in the presence of power-law temporally correlated noise. By means of extensive numerical simulations of models in the KPZ universality class we find that, as the ...
Generalized fluctuation relation for power-law distributions
(American Physical Society, 2012-07)
Strong violations of existing fluctuation theorems may arise in nonequilibrium steady states characterized by distributions with power-law tails. The ratio of the probabilities of positive and negative fluctuations of equal ...
Planar generalized electrodynamics for one-loop amplitude in the Heisenberg picture
(2021-07-10)
We examine the generalized quantum electrodynamics as a natural extension of the Maxwell electrodynamics to cure the one-loop divergence. We establish a precise scenario to discuss the underlying features between photon ...
Exponential distributed time-delay nonlinear models: Monte Carlo simulations
(Elsevier Science, 2014-04)
The stochastic dynamics toward the final attractor in an exponential distributed time-delay nonlinear model is studied, in the small noise approximation. The passage time statistic for this non-Markovian type of system has ...
Real-time approach to tunnelling in open quantum systems: Decoherence and anomalous diffusion
(IOP Publishing, 2006-12)
Macroscopic quantum tunnelling is described using the master equation for the reduced Wigner function of an open quantum system at zero temperature. Our model consists of a particle trapped in a cubic potential interacting ...
Surface super-roughening driven by spatiotemporally correlated noise
(IOP Publishing, 2020-03)
We study the simple, linear, Edwards-Wilkinson equation that describes surface growth governed by height diffusion in the presence of spatiotemporally power-law decaying correlated noise. We analytically show that the ...
Anomalous transport induced by nonhyperbolicity
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
In this paper we study how deterministic features presented by a system can be used to perform direct transport in a quasisymmetric potential and weak dissipative system. We show that the presence of nonhyperbolic regions ...
