Numerical studies of transport in complex many-particle systems far from equilibrium

2012

In this Thesis, transport in complex nonequilibrium many-particle systems is studied using numerical master equation approach and Monte Carlo simulations. We focus on the transport of the center-of-mass of deformable objects with internal structure. Two physical systems are studied in detail: linear polymers using the Rubinstein-Duke model and single-layer metal-on-metal atomic islands using a semi-empirical lattice model. Polymers and islands are driven out of thermodynamic equilibrium by strong static and time-dependent external forces. Topics covered in this work include introductions to nonequilibrium statistical mechanics, master equations and computational methods, with construction a…
