Thermalization and its mechanism for generic isolated quantum systems
Nature, 2007An understanding of the temporal evolution of isolated many-body quantum systems has long been elusive. Recently, meaningful experimental studies of the problem have become possible, stimulating theoretical interest.

Equilibrium Statistical Mechanics
2002In this section we review the entropy principle, which may serve as a basis for deriving various assemble density functions. The principle has a long history and has been the topic of controversy over many years. Although the starting point is rather simple, it lasted a few decades before the correct mathematical formulation was obtained and that the ...

Equilibrium Statistical Mechanics
2019AbstractChapter 4 reviews the basic notions of equilibrium statistical mechanics and begins with its fundamental postulate and outlines the structure of the theory using the most important of the various statistical ensembles, the microcanonical, the canonical, and the grand canonical ensemble and their corresponding thermodynamic potential, the ...

Mechanical Equilibrium and Equilibrium Systems
2003In the paper, it is shown that the principle of virtual work considered an axiom of mechanics by Lagrange (1788) and Farkas (1906) can be embedded in a general equilibrium system, the quasi-variational inequalities introduced by Bensoussan and Lions in 1973, assuming force fields and holonomic-scleronomic constraints.

Mechanical equilibrium of conformal crystals
Physical Review E, 1996The relation between a conformal mapping and the geometrical features of the conformal lattice it defines is analyzed. The field created by particles interacting via inverse power law forces and located in the vortices of the conformal lattice is determined.

Equilibrium Selling Mechanisms [PDF]
Annals of Economics and Finance, 2004 We consider the equilibrium choice of selling mechanisms by competing firms. For a model where a number of sellers choose sequentially between any two selling mechanisms, there is a unique (subgame perfect) equilibrium under fairly natural assumptions about the monotonicity and differences of the two mechanisms.

Equilibrium Statistical Mechanics
1976In this chapter we wish to consider a general system (with a fixed number of particles) in thermal equilibrium. The system may either be isolated from its environment (and therefore at constant energy) or be in contact with a thermal reservoir at temperature T. The system at constant energy will in fact never be completely isolated and should therefore

Equilibrium Statistical Mechanics
2001In Chapter 2, we established the equations governing the microscopic dynamics of the lattice gas. This microscopic dynamics provides the basics of the procedure for constructing automata simulating the behavior of fluid systems (see Chapter 10). However, in order to use LGAs as a method for the analysis of physical phenomena, we must go to a level of ...
