Critical dynamics of gauge systems: Spontaneous vortex formation in 2D superconductors

Autor: Stephens, G. J., Bettencourt, Luis M. A., Zurek, W. H.

Publikováno v: Phys.Rev.Lett.88:137004,2002

We examine the formation of vortices during the nonequilibrium relaxation of a high-temperature initial state of an Abelian-Higgs system. We equilibrate the scalar and gauge fields using gauge-invariant Langevin equations and relax the system by inst

Notes on Black Hole Phase Transitions

Autor: Stephens, G. J., Hu, B. L.

Publikováno v: Int.J.Theor.Phys. 40 (2001) 2183-2200

In these notes we present a summary of existing ideas about phase transitions of black hole spacetimes in semiclassical gravity and offer some thoughts on three possible scenarios by which these transitions could take place. Our first theme is ilustr

Defect Formation and Critical Dynamics in the Early Universe

Autor: Stephens, G. J., Calzetta, E. A., Hu, B. L., Ramsey, S. A.

Publikováno v: Phys.Rev. D59 (1999) 045009

We study the nonequilibrium dynamics leading to the formation of topological defects in a symmetry-breaking phase transition of a quantum scalar field with \lambda\Phi^4 self-interaction in a spatially flat, radiation-dominated Friedmann-Robertson-Wa
