Non-equilibrium Particle Dynamics with Unbounded Number of Interacting Neighbors

Particle-Dynamics Approach to Non-Equilibrium Phenomena

A particle-dynamics simulation is a tool for investigating nonequilibrium phenomena accompanied with hydrodynamic, thermodynamic motions, and even with phase transitions. In this article, several applications of the particledynamics simulation and a new computational method of particle dynamics are reported.

Equilibrium dynamics of continuous unbounded spin systems

Influence of the number of topologically interacting neighbors on swarm dynamics

Recent empirical and theoretical works on collective behaviors based on a topological interaction are beginning to offer some explanations as for the physical reasons behind the selection of a particular number of nearest neighbors locally affecting each individual's dynamics. Recently, flocking starlings have been shown to topologically interact with a very specific number of neighbors, betwee...

Interacting particle systems out of equilibrium

These notes are based on lectures delivered by the authors at the Langeoog seminar of SFB/TR12 Symmetries and universality in mesoscopic systems in November 2007, to a mixed audience of mathematicians and theoretical physicists. After a brief outline of the basic physical concepts of equilibrium and nonequilibrium states, the one-dimensional totally asymmetric simple exclusion process (TASEP) i...

Strongly Interacting Fermi Gases: Non-Equilibrium Dynamics and Dimensional Crossover

Experiments using ultracold atomic gases address fundamental problems in manybody physics. This thesis describes experiments on strongly-interacting gases of fermionic atoms, with a focus on non-equilibrium physics and dimensionality. One of the fundamental dissipative processes in two-component gases is the transport of spin due to relative motion between the two spin components. We generate s...
