Unifying description of the damping regimes of a stochastic particle in a periodic potential
Antonio Piscitelli, Massimo Pica Ciamarra
We analyze the classical problem of the stochastic dynamics of a particle confined in a periodic potential, through the so called Il'in and Khasminskii model, with a novel semi-ana…
Escape rate and diffusion of a random walker
Massimo Pica Ciamarra, Antonio Piscitelli
We determine the rate of escape from a potential well, and the diffusion coefficient in a periodic potential, of a random walker that moves under the influence of the potential in…
Singular behavior of fluctuations in a relaxation process
Federico Corberi, Giuseppe Gonnella, Antonio Piscitelli
Carrying out explicitly the computation in a paradigmatic model of non-interacting systems, the Gaussian Model, we show the existence of a singular point in the probability distrib…
Energy and Heat Fluctuations in a Temperature Quench
M. Zannetti, F. Corberi, G. Gonnella +1
Fluctuations of energy and heat are investigated during the relaxation following the instantaneous temperature quench of an extended system. Results are obtained analytically for t…
Heat exchanges in a quenched ferromagnet
Federico Corberi, Giuseppe Gonnella, Antonio Piscitelli +1
The off-equilibrium probability distribution of the heat exchanged by a ferromagnet in a time interval after a quench below the critical point is calculated analytically in the lar…
Fluctuation relations in non-equilibrium stationary states of Ising models
A. Piscitelli, F. Corberi, G. Gonnella +1
Fluctuation relations for the entropy production in non equilibrium stationary states of Ising models are investigated by Monte Carlo simulations. Systems in contact with heat bath…
Heat fluctuations in Ising models coupled with two different heat baths
A. Piscitelli, F. Corberi, G. Gonnella
Monte Carlo simulations of Ising models coupled to heat baths at two different temperatures are used to study a fluctuation relation for the heat exchanged between the two thermost…
