Driven Lorentz model in discrete time
Dan Shafir, Alessio Squarcini, Stanislav Burov +1
We consider a tracer particle performing a random walk on a two-dimensional lattice in the presence of immobile hard obstacles. Starting from equilibrium, a constant force pulling…
Time-dependent dynamics in the confined lattice Lorentz gas
A. Squarcini, A. Tinti, P. Illien +2
We study a lattice model describing the non-equilibrium dynamics emerging from the pulling of a tracer particle through a disordered medium occupied by randomly placed obstacles. T…
Four-point interfacial correlation functions in two dimensions. Exact results from field theory and numerical simulations
Alessio Squarcini, Antonio Tinti
We derive exact analytic results for several four-point correlation functions for statistical models exhibiting phase separation in two-dimensions. Our theoretical results are then…
Correlations and structure of interfaces in the Ising model. Theory and numerics
Alessio Squarcini, Antonio Tinti
We consider phase separation on the strip for the two-dimensional Ising model in the near-critical region. Within the framework of field theory, we find exact analytic results for…
Interface in presence of a wall. Results from field theory
Gesualdo Delfino, Marianna Sorba, Alessio Squarcini
We consider three-dimensional statistical systems at phase coexistence in the half-volume with boundary conditions leading to the presence of an interface. Working slightly below t…
Particles, string and interface in the three-dimensional Ising model
Gesualdo Delfino, Walter Selke, Alessio Squarcini
We consider the three-dimensional Ising model slightly below its critical temperature, with boundary conditions leading to the presence of an interface. We show how the interfacial…
