Weak uncorrelated quenched disorder drives the topological transition of the 3D Z2 gauge model into a new universality class, consistent with the Harris criterion.
Quantum quenches in the Ising chain exhibit qualitatively distinct out-of-equilibrium dynamics when crossing continuous versus first-order quantum transitions depending on the transverse field strength.
