Anti-de Sitter Space, Thermal Phase Transition, and Confinement in Gauge Theories

by Edward Witten - Adv. Theor. Math. Phys , 1998
"... The correspondence between supergravity (and string theory) on AdS space and boundary conformal field theory relates the thermodynamics of N = 4 super Yang-Mills theory in four dimensions to the thermodynamics of Schwarzschild black holes in Anti-de Sitter space. In this description, quantum phenome ..."

The correspondence between supergravity (and string theory) on AdS space and boundary conformal field theory relates the thermodynamics of N = 4 super Yang-Mills theory in four dimensions to the thermodynamics of Schwarzschild black holes in Anti-de Sitter space. In this description, quantum phenomena such as the spontaneous breaking of the center of the gauge group, magnetic confinement, and the mass gap are coded in classical geometry. The correspondence makes it manifest that the entropy of a very large AdS Schwarzschild black hole must scale “holographically ” with the volume of its horizon. By similar methods, one can also make a speculative proposal for the description of large N gauge theories in four dimensions without supersymmetry. March

PHASE TRANSITION

by J. R. Anglin A, W. H. Zurek B , 2000
"... A rapid second order phase transition can have a significant probability of producing a metastable state instead of the equilibrium state. We consider the case of rapid Bose-Einstein condensation in a toroidal trap resulting in a spontaneous superfluid current, and compare the phenomenological time- ..."

The phase transition in inhomogeneous random graphs

by Bela Bollobás, Svante Janson, Oliver Riordan , 2005
"... The ‘classical’ random graph models, in particular G(n, p), are ‘homogeneous’, in the sense that the degrees (for example) tend to be concentrated around a typical value. Many graphs arising in the real world do not have this property, having, for example, power-law degree distributions. Thus there ..."

there has been a lot of recent interest in defining and studying ‘inhomogeneous ’ random graph models. One of the most studied properties of these new models is their ‘robustness’, or, equivalently, the ‘phase transition ’ as an edge density parameter is varied. For G(n, p), p = c/n, the phase transition

PHASE TRANSITION

by unknown authors , 1997
"... Light stops can give a strong first order electroweak phase transition in the Minimal Supersymmetric Standard Model (MSSM) satisfying one of the necessary conditions for electroweak baryogenesis. I discuss the region of parameter space where this occurs using a perturbative analysis of the Higgs eff ..."

On phase transition in . . .

by David Galvin, Jeff Kahn
"... It is shown that the hard-core model on Z d exhibits a phase transition at activities above some function λ(d) which tends to zero as d → ∞; that is: Consider the usual nearest neighbor graph on Z d, and write E and O for the sets of even and odd vertices (defined in the obvious way). Set ΛM = Λ d M ..."
