Quantum-thermal self-diffusion as a hydrodynamic mechanism for the fluctuation relaxation
O. N. Golubjeva, S. V. Sidorov
We propose a generalization of quantum mechanical equations in the hydrodynamic form by introducing, into the Lagrangian density, terms taking into account the diffusion velocity a…
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…
Quantum-thermal fluctuations of effective macroparameters and their correlations
A. D. Sukhanov, O. N. Golubjeva, V. G. Baryakhtar
The application of the conventional theory of macroparameter fluctuations has been shown to go beyond the framework of the thermodynamic description in a number of cases. The princ…
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…
New version of quantum mechanics at finite temperatures as a ground for description of nearly perfect fluids
A. D. Sukhanov, O. N. Golubjeva
We suggest a more general than quantum statistical mechanics () microdescription of objects in a heat bath taken into account a vacuum as an object environment - modification…
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…
