Abstract

Using Monte Carlo methods, I study the thermodynamic properties of Z_2 Abelian lattice gauge theory in flat, homogeneous, isotropic, expanding spacetimes characterized by the scale factor a(t). The presence of the scale factor introduces a spacelike domain wall inside the four dimensional spacetime lattice where the phase transition associated with deconfinement occurs. The resulting theory appears identical to introducing a time-dependent effective coupling beta_eff, and could serve as a simple model for the electroweak phase transition of the early Universe.

  1. The joys of having a Forever Project 1 comment

    • Take me as an example. My Forever Project is Physics. I have a degree in both CS and Physics. I made the decision years ago to work in the industry as a programmer, because it's more fun and pays better than being an academic, especially where I live. I'm not officially involved…
