Residence time in presence of moving defects and obstacles
E. N. M. Cirillo, M. Colangeli, A. Di Francesco
We discuss the properties of the residence time in presence of moving defects or obstacles for a particle performing a one dimensional random walk. More precisely, for a particle c…
Highly anisotropic scaling limits
Marzio Cassandro, Matteo Colangeli, Errico Presutti
We consider a highly anisotropic Ising spin model whose precise definition can be found at the beginning of Section 2. In this model the spins on a same horizontal line (laye…
A Kac Model for Fermions
M. Colangeli, F. Pezzotti, M. Pulvirenti
We introduce a stochastic -particle system and show that, as , an effective description ruled by the homogeneous fermionic Uehling-Uhlenbeck equation is recovered.…
Steady state fluctuation relation and time-reversibility for non-smooth chaotic maps
Matteo Colangeli, Rainer Klages, Paolo De Gregorio +1
Steady state fluctuation relations for dynamical systems are commonly derived under the assumption of some form of time-reversibility and of chaos. There are, however, cases in whi…
A meaningful expansion around detailed balance
Matteo Colangeli, Christian Maes, Bram Wynants
We consider Markovian dynamics modeling open mesoscopic systems which are driven away from detailed balance by a nonconservative force. A systematic expansion is obtained of the st…
