Topological relics of symmetry breaking: winding numbers and scaling tilts from random vortex-antivortex pairs by Zurek, W H

“…I show that random distributions of vortex-antivortex pairs (rather than of individual vortices) lead to scaling of typical winding numbers W trapped inside a…”

Decoherence and the Loschmidt echo by Cucchietti, F M, Dalvit, D A R, Paz, J P, Zurek, W H

“…Decoherence causes entropy increase that can be quantified using, e.g., the purity sigma=Trrho(2). When the Hamiltonian of a quantum system is perturbed, its…”
