Uncovering gauge-dependent critical order-parameter correlations by a stochastic gauge fixing at and continuous transitions
We study the O (N)* transitions that occur in the 3D Z 2-gauge N-vector model and the
analogous Ising* transitions occurring in the 3D Z 2-gauge Higgs model, corresponding to …
