Abstract

The quantum oscillator in the thermostat is considered as the model of an\nopen quantum system. Our analysis will be heavily founded on the use of the\nSchroedinger generalized uncertainties relations (SUR). Our first aim is to\ndemonstrate that for the quantum oscillator the state of thermal equilibrium\nbelongs to the correlated coherent states (CCS), which imply the saturation of\nSUR at any temperature. The obtained results open the perspective for the\nsearch of some statistical theory, which unifies the elements of quantum\nmechanics and GDT; this in turn will give the foundation for the modification\nof the standard thermodynamics.\n
