Quantum mechanics as classical statistical mechanics with an ontic extension and an epistemic restriction [PDF]

open access: yesNature Communications, 2017
Where does quantum mechanics part ways with classical statistical mechanics? Here the authors derive both within a common framework; the former differs from the latter by an ontic nonseparable random variable and a restriction on the allowed phase space ...

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

open access: yesEPJ 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.

Non-extensive statistical mechanics and black hole entropy from quantum geometry [PDF]

open access: yesPhysics Letters B, 2017
Using non-extensive statistical mechanics, the Bekenstein–Hawking area law is obtained from microstates of black holes in loop quantum gravity, for arbitrary real positive values of the Barbero–Immirzi parameter (γ).

Statistical mechanics model for Clifford random tensor networks and monitored quantum circuits [PDF]

open access: yesPhysical review B, 2021
We introduce an exact mapping of Clifford (stabilizer) random tensor networks (RTNs) and monitored quantum circuits, onto a statistical mechanics model.

Developments in the Tensor Network — from Statistical Mechanics to Quantum Entanglement [PDF]

open access: yesJournal of the Physical Society of Japan, 2021
Tensor networks (TNs) have become one of the most essential building blocks for various fields of theoretical physics such as condensed matter theory, statistical mechanics, quantum information, and quantum gravity.

Some speculations about local thermalization of nonequilibrium extended quantum systems

open access: yesCondensed 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

open access: yesNature 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

open access: yesPhysical 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

open access: yesEntropy, 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.
