Numerical simulations confirm that the 3D SU(2) gauge glass model retains O(4) universality for the ferromagnetic-paramagnetic transition under weak disorder and shows disorder-independent universal behavior at the paramagnetic-spin glass transition.
A review of equilibrium and dynamic scaling laws at quantum phase transitions, including quenches and dissipative effects treated as perturbations to critical regimes.
