Query: Monte Carlo study of a vortex glass model   We describe results of Monte Carlo simulations on a model that seems to have
the necessary ingredients to describe a disordered type-II superconductor in a
magnetic field. We compute the free energy cost to twist the direction of the
phase of the condensate and analyze the results by finite-size scaling. The
results show convincingly that the model has different behavior as a function
of dimension: in $d=4$ the model clearly has a finite transition temperature;
$T_c$, while for $d=2$ only there is only a transition at $T=0$.
