Equation of State and Statistical Distribution in a Macroscopic System

A representation is proposed for the statistical sum for a macroscopic body in the form of a Euclidean functional integral in which the body deformation is a classical fluctuation-free parameter. The equation of state of the body relating its deformation and temperature with the external mechanical...

Beschreibung
Zusammenfassung:	A representation is proposed for the statistical sum for a macroscopic body in the form of a Euclidean functional integral in which the body deformation is a classical fluctuation-free parameter. The equation of state of the body relating its deformation and temperature with the external mechanical load is contained in this representation as a constraint on the integration measure by a suitable classical equation of motion.
