Critical phenomena and functional renormalization group

open access: yesHe jishu, 2023
Recent progress in studies on quantum chromodynamics (QCD) phase transition and related critical phenomena within the functional renormalization group (fRG) approach were reviewed, including the nonperturbative critical exponents and baryon number ...

Observation of Critical Phenomena in Parity-Time-Symmetric Quantum Dynamics. [PDF]

open access: yesPhysical Review Letters, 2018
We experimentally simulate nonunitary quantum dynamics using a single-photon interferometric network and study the information flow between a parity-time- (PT-)symmetric non-Hermitian system and its environment.

Percolation Theories for Quantum Networks

open access: yesEntropy, 2023
Quantum networks have experienced rapid advancements in both theoretical and experimental domains over the last decade, making it increasingly important to understand their large-scale features from the viewpoint of statistical physics. This review paper

Derivation of the Critical Point Scaling Hypothesis Using Thermodynamics Only

open access: yesEntropy, 2020
Based on the foundations of thermodynamics and the equilibrium conditions for the coexistence of two phases in a magnetic Ising-like system, we show, first, that there is a critical point where the isothermal susceptibility diverges and the specific heat

Connecting Complex Electronic Pattern Formation to Critical Exponents

open access: yesCondensed Matter, 2021
Scanning probes reveal complex, inhomogeneous patterns on the surface of many condensed matter systems. In some cases, the patterns form self-similar, fractal geometric clusters. In this paper, we advance the theory of criticality as it pertains to those

Brownian non-Gaussian polymer diffusion and queuing theory in the mean-field limit

open access: yesNew Journal of Physics, 2022
We link the Brownian non-Gaussian diffusion of a polymer center of mass (CM) to a microscopic cause: the polymerization/depolymerization phenomenon occurring when the polymer is in contact with a monomer chemostat.

Critical phenomena in Newtonian gravity [PDF]

open access: yes, 2001
We investigate the stability of self-similar solutions for a gravitationally collapsing isothermal sphere in Newtonian gravity by means of a normal mode analysis.

Critical phenomena of charged de Sitter black holes in cavities [PDF]

open access: yesClassical and quantum gravity, 2018
We examine the thermodynamic behaviour of four-dimensional charged and uncharged de Sitter black holes enclosed in an isothermal cavity, in the extended phase space where the cosmological constant is treated as a thermodynamic pressure.

Phase transitions associated with economy and demography [PDF]

open access: yesКомпьютерные исследования и моделирование, 2010
Crises in social systems are considered by analogy with phase transitions and the corresponding critical phenomena in «non-living» many-particle physical systems.

Critical phenomena and chemical potential of a charged AdS black hole [PDF]

open access: yes, 2017
We study the thermodynamics and the chemical potential for a five-dimensional charged AdS black hole by treating the cosmological constant as the number of colors $N$ in the boundary gauge theory and its conjugate quantity as the associated chemical ...
