Thermal Equilibrium Distribution of Wavefunctions
نویسنده
چکیده
It is well known that in quantum theory, thermal equilibrium at inverse temperature β corresponds to the density matrix (1/Z) exp(−βH). But a density matrix that is not pure can arise from many different distributions of the wavefunction. We address in this paper the question which distribution of the wavefunction corresponds to thermal equilibrium, or, in other words, which distribution of the wavefunction represents the canonical ensemble. We propose here, and argue for, a specific candidate.

متن کاملNon-equilibrium in Stochastic Mechanics
The notion of non-equilibrium, in the sense of a particle distribution other than ρ = |ψ|, is imported into Nelson’s stochastic mechanics, and described in terms of effective wavefunctions obeying non-linear equations. These techniques are applied to the discussion of non-locality in non-linear Schrödinger equations.

In this research, effect of swarf addition on the microstructure of die cast aluminum A380 alloy and the possibility of altering the alloy structure in the metallic die has been studied. The microstructure mainly consists of the α-phase, eutectic, intermetallic compounds and porosity. Since the alloy solidifies under non-equilibrium conditions, the Scheil equation with exact amount of equilibri...

The Effect of Temperature Dependency on the Thermo-Electro-Elastic Analysis of Functionally Graded Piezoelectric Spherical Shell
Results of electro-thermo-elastic analysis of a functionally graded thick-walled spherical shell made of temperature dependent materials are presented in this article. All material properties are assumed temperature-dependent and also are graded along the thickness direction based on power function. Temperature dependency is accounted for all material properties including, thermal, mechanical a...
