Localization induced by Sinai disorder in mass-exchange models
Michele Giusfredi, Luca Avena, Paolo Politi
We introduce a conservative continuous-mass-exchange model with quenched disorder in the splitting laws on the bonds of a finite segment. Although the dynamics is generically irrev…
Generalized diffusion theory for radiative transfer in fully anisotropic scattering media
Ernesto Pini, Michele Giusfredi, Lorenzo Pattelli
A generalized anisotropic-diffusion framework is developed for transport problem in media described by a tensorial scattering coefficient and a scalar Henyey--Greenstein asymmetry…
Mean-field theory of the DNLS equation at positive and negative absolute temperatures
Michele Giusfredi, Stefano Iubini, Antonio Politi +1
The Discrete Non Linear Schrödinger (DNLS) model, due to the existence of two conserved quantities, displays an equilibrium transition between a homogeneous phase at positive absol…
Infinite-temperature thermostats by energy localization in a nonequilibrium setup
Michele Giusfredi, Stefano Iubini, Antonio Politi +1
Some lattice models having two conservation laws may display an equilibrium phase transition from a homogeneous (positive temperature - PT) to a condensed (negative temperature) ph…
Localization in boundary-driven lattice models
Michele Giusfredi, Stefano Iubini, Paolo Politi
Several systems display an equilibrium condensation transition, where a finite fraction of a conserved quantity is spatially localized. The presence of two conservation laws may in…
