Symmetric boundary conditions in boundary critical phenomena [PDF]

open access: yes, 1999
Conformally invariant boundary conditions for minimal models on a cylinder are classified by pairs of Lie algebras $(A,G)$ of ADE type. For each model, we consider the action of its (discrete) symmetry group on the boundary conditions.

Critical phenomena for systems under constraint

open access: yesCondensed Matter Physics, 2014
It is well known that the imposition of a constraint can transform the properties of critical systems. Early work on this phemomenon by Essam and Garelick, Fisher, and others, focused on the effects of constraints on the leading critical exponents ...

Fenômenos críticos: 150 anos desde Cagniard de la Tour

open access: yesRevista Brasileira de Ensino de Física
Em 1822 o cientista francês Caignard de la Tour descobriu os fenômenos críticos. Com o intuito de comemorar os 150 anos do aniversário de sua morte, revisamos neste artigo o contexto e a história inicial de sua descoberta.

The Theory of Boundary Critical Phenomena [PDF]

open access: yesInternational Journal of Modern Physics B, 1997
An introduction into the theory of boundary critical phenomena and the application of the field-theoretical renormalization group method to these is given. The emphasis is on a discussion of surface critical behavior at bulk critical points of magnets, binary alloys, and fluids. Yet a multitude of related phenomena are mentioned.

Black Hole Critical Phenomena Without Black Holes [PDF]

open access: yes, 2000
Studying the threshold of black hole formation via numerical evolution has led to the discovery of fascinating nonlinear phenomena. Power-law mass scaling, aspects of universality, and self-similarity have now been found for a large variety of models ...

Carnot Cycles in a Harmonically Confined Ultracold Gas across Bose–Einstein Condensation

open access: yesEntropy, 2023
Carnot cycles of samples of harmonically confined ultracold 87Rb fluids, near and across Bose–Einstein condensation (BEC), are analyzed. This is achieved through the experimental determination of the corresponding equation of state in terms of the ...

Dynamic critical phenomena at a holographic critical point

open access: yes, 2011
We study time-dependent perturbations to a family of five-dimensional black hole spacetimes constructed as a holographic model of the QCD phase diagram.

Analytical and exact critical phenomena of d-dimensional singly spinning Kerr-AdS black holes [PDF]

open access: yes, 2015
In the extended phase space, the $d$-dimensional singly spinning Kerr-anti--de Sitter black holes exhibit the van der Waals phase transition and reentrant phase transition.

Critical phenomena of thick branes in warped spacetimes [PDF]

open access: yes, 2001
We have investigated the effects of a generic bulk first-order phase transition on thick Minkowski branes in warped geometries. As occurs in Euclidean space, when the system is brought near the phase transition an interface separating two ordered phases ...
