Abstract

The statistical mechanics of small systems is considered, where by virtue of physical or geometric limitations it is impossible to realize the transition to the thermodynamic limit. Fundamental effects are discussed which distinguish small equilibrium systems from large equilibrium systems: non-equivalence of ensembles, nonadditivity of thermodynamic potentials, the influence of fluctuations, complexity of the description of phase transitions. Along with a general analysis of features of the thermodynamic behavior of small systems, corresponding results are presented for the problem of adsorption of a gas on a surface.
