Quantum statistical mechanics of vortices [PDF]

Journal of Physics A: Mathematical and Theoretical, 2022
Abstract The asymptotic partition function for quantized abelian Higgs vortices at high temperature T is found to leading and subleading order, and from this the equation of state of the vortex gas is derived, including the first quantum correction.

A new statistical thermodynamic mechanism for quantum mechanics

Frontiers in Physics, 2022
A new quantum mechanics mechanism theory based on statistical mechanics is introduced. This theory is based on corresponding changes in the number of states with associated energy changes at the observer and observed occurring at observer 1) reset and 2)

The Group-Algebraic Formalism of Quantum Probability and Its Applications in Quantum Statistical Mechanics [PDF]

Entropy
We show that the theory of quantum statistical mechanics is a special model in the framework of the quantum probability theory developed by mathematicians, by extending the characteristic function in the classical probability theory to the quantum ...

The Born Rule—100 Years Ago and Today [PDF]

Entropy
The details of the contents and formulations of the Born rule have changed considerably from its inception by Born in 1926 to the present day. This paper traces the early history of the Born rule 100 years ago, its generalization (essential for today’s ...

Disorder-induced quantum-to-classical transition, or how the world becomes classical [PDF]

EPJ Web of Conferences, 2022
Decoherence theory explains how quantum mechanics gives rise to classical mechanics through the entanglement of a quantum system’s evolution with the degrees of freedom of the environment.

Some speculations about local thermalization of nonequilibrium extended quantum systems

Condensed Matter Physics, 2023
We discuss the possibility of defining an emergent local temperature in extended quantum many-body systems evolving out of equilibrium. For the most simple case of free-fermionic systems, we give an explicit formula for the effective temperature in the ...

Exceptional dynamical quantum phase transitions in periodically driven systems

Nature Communications, 2021
Understanding phase transitions in systems out of equilibrium is a topic of high interest. Here the author discusses the spontaneous antiunitary symmetry breaking leading to exceptional dynamical quantum phase transitions in driven many-body systems.

Statistical mechanics for non-Hermitian quantum systems

Physical Review Research, 2023
We present a systematic study of statistical mechanics for non-Hermitian quantum systems. Our work reveals that the stability of a non-Hermitian system necessitates the existence of a single path-dependent conserved quantity, which, in conjunction with ...

Gas of Particles Obeying the Monotone Statistics

Entropy, 2023
The present note is devoted to the detailed investigation of a concrete model satisfying the block-monotone statistics introduced in a previous paper (joint, with collaborators) of the author.

Hybrid classical-quantum computing: Applications to statistical mechanics of financial markets [PDF]

E3S Web of Conferences, 2021
Hybrid Classical-Quantum computing is now offered by several commercial quantum computers. In this project, a model of financial options, Statistical Mechanics of Financial Markets (SMFM), uses this approach. However, only Classical (super-)computers are
