Schrödinger uncertainty relation for a quantum oscillator in a thermostat

Abstract: We introduce the Schrödinger correlator as the holistic characteristic of two types of fluctuation correlations in quantum dynamics and in statistical thermodynamics. We are the first to derive it using methods of thermofield dynamics for the coordinate-momentum variables of a quantum oscillator in a thermostat. We show that the obtained value ensures that the Schrödinger uncertainty relation becomes an equality at all temperatures. We find that the thermal equilibrium for the quantum oscillator has the sense … Show more

“…Standard von Neumann expression (37) for the entropy accepted in QESM turns out to be semiclassical and is therefore inadequate for use over the entire temperature range. At the same time, expression (35) following from definition (34) in our proposed TFD version and expressions (15) and (26) in the QGEST are in agreement, and we can use them to determine the effective entropy S * by independent methods adequately accounting for both types of stochastic actions at any temperature.…”

“…In this paper, which is a continuation of [13], where we introduced the original notions of kD, we develop this theory further as a microdescription of an object under thermal equilibrium conditions. It is based on a new microparameter, namely, the stochastic action operator.…”
