Correlated Coherent States - Quantum Analogue Of Thermal States.(On The Problem Of Incorporating Thermodynamics Into Quantum Theory)
A. D. Sukhanov, O. N. Golubjeva, V. G. Bar'yakhtar
In this paper, we show that correlated coherent states (CCSs) are the most adequate candidates for the role of quantum analogues of the thermal states. The main result of our study…

Equations of one-dimensional hydrodynamics with quantum thermal fluctuations taken into account
O. N. Golubjeva, A. D. Sukhanov, V. G. Bar'yakhtar
We propose a generalization of equations of quantum mechanics in the hydrodynamic form by introducing the terms taking into account the diffusion velocity at zero and finite temper…

Modified Thermodynamics as an Approach to the Description of some Universal Properties of "Nearly Perfect Fluids"
A. D. Sukhanov, V. G. Bar'yakhtar, O. N. Golubjeva
We show that the quantum statistical mechanics describing quantum and thermal properties of objects has only the sense of a particular semiclassical approximation. We propose a mor…
