Critical Phenomena in Gravitational Collapse [PDF]

Living Reviews in Relativity, 2007
As first discovered by Choptuik, the black hole threshold in the space of initial data for general relativity shows both surprising structure and surprising simplicity.

Parity-time-symmetric quantum critical phenomena [PDF]

Nature Communications, 2017
Parity-time (PT) symmetry has been mainly studied in optical and weakly interacting open quantum systems without many-body correlations. Here the authors show that in a strongly correlated many-body system the interplay between correlations and PT ...

Unification of the Nature’s Complexities via a Matrix Permanent—Critical Phenomena, Fractals, Quantum Computing, ♯P-Complexity [PDF]

Entropy, 2020
We reveal the analytic relations between a matrix permanent and major nature’s complexities manifested in critical phenomena, fractal structures and chaos, quantum information processes in many-body physics, number-theoretic complexity in ...

Ralph Kenna’s Scaling Relations in Critical Phenomena [PDF]

Entropy
In this note, we revisit the scaling relations among “hatted critical exponents”, which were first derived by Ralph Kenna, Des Johnston, and Wolfhard Janke, and we propose an alternative derivation for some of them. For the scaling relation involving the

Effects of inclusions and the presence of an adsorbing surface on lateral and flip-flop phase transitions in fluid membranes

Scientific African, 2021
In this paper, we first investigate the effects of inclusions on the critical behavior of a fluid bilayer biomembrane made of two incompatible amphiphiles A and B.

Dynamic structure factors of fluid membranes exhibiting lateral and flip-flop transitions: Effects of inclusions and the presence of an interacting wall

Scientific African, 2021
In this paper, we consider a fluid membrane formed by a mixture of two chemically incompatible lipid molecules A and B. The variation of an adequate parameter (temperature, PH, lateral pressure, etc.) may lead the amphiphile molecules of the bilayer to ...

Superconducting Quantum Critical Phenomena [PDF]

Reports in Advances of Physical Sciences, 2018
When the superconducting transition temperature Tc sufficiently approaches zero, quantum fluctuations are expected to be overwhelmingly amplified around zero temperature so that the mean-field approximation may break down.

The effect of non-local derivative on Bose-Einstein condensation

Condensed Matter Physics, 2021
In this paper, we study the effect of non-local derivative on Bose-Einstein condensation. Firstly, we consider the Caputo-Fabrizio derivative of fractional order α to derive the eigenvalues of non-local Schrödinger equation for a free particle in a 3D ...

Critical phenomena and functional renormalization group

He 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 ...

Derivation of the Critical Point Scaling Hypothesis Using Thermodynamics Only

Entropy, 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
