First passage time for superstatistical Fokker-Planck models
Adrián A. Budini, Manuel O. Cáceres
The first passage time (FPT) problem is studied for superstatistical models assuming that the mesoscopic system dynamics is described by a Fokker-Planck equation. We show that all…
Observing the evaporation transition in vibro-fluidized granular matter
Jorge E. Fiscina, Manuel O. Caceres
By shaking a sand box the grains on the top start to jump giving the picture of evaporating a sand bulk, and a gaseous transition starts at the surface granular matter (GM) bed. Mo…
On the spectrum behavior of vibrated granular matter
Jorge E. Fiscina, Manuel O. Caceres, Frank Muecklich
A laser facility based on a linear image sensor with a sampling period of 100microseconds allows to investigate the dissipative dynamics of a vibrated granular matter under gravity…
Multifractal spectra of mean first-passage time distributions in disordered chains
Pedro A. Pury, Manuel O. Caceres
The multifractal characterization of the distribution over disorder of the mean first-passage time in a finite chain is revisited. Both, absorbing-absorbing and reflecting-absorbin…
Mean first-passage and residence times of random walks on asymmetric disordered chains
Pedro A. Pury, Manuel O. Caceres
An algebraic derivation is presented which yields the exact solution of the mean first-passage and mean residence times of a one-dimensional asymmetric random walk for quenched dis…
Survival and residence times in disordered chains with bias
Pedro A. Pury, Manuel O. Caceres
We present a unified framework for first-passage time and residence time of random walks in finite one-dimensional disordered biased systems. The derivation is based on exact expan…
