Equilibration in the Nosé–Hoover Isokinetic Ensemble: Effect of Inter-Particle Interactions

Autor: Shamik Gupta, Stefano Ruffo

Publikováno v: Entropy, Vol 19, Iss 10, p 544 (2017)

We investigate the stationary and dynamic properties of the celebrated Nosé–Hoover dynamics of many-body interacting Hamiltonian systems, with an emphasis on the effect of inter-particle interactions. To this end, we consider a model system with b

A evolução dos sistemas auto-gravitacionais para estados estacionários fora de equilíbrio ocorre através do mecanismo de relaxação violenta, um processo pelo qual partículas trocam energia por estarem se movendo em um potencial dependente do

International audience; Globally-coupled N-body systems are well-known to possess an intricate dynamics. When N is large, collective effects may drastically lower the effective dimension of the dynamics breaking the conditions on ergodicity necessary

For a many-particle system with long-range interactions and evolving under stochastic dynamics, we study for the first time the out-of-equilibrium fluctuations of the work done on the system by a time-dependent external force. For equilibrium initial

Systems of particles interacting with long range interactions present generically ”quasi-stationary states” (QSS), which are approximately time-independent out of equilibrium states. In this proceedings, we explore the generalization of the forma
