Zurek's scaling-law in the Ising model out of thermal equilibrium
José Armando Pérez-Loera, Wolfgang Bietenholz
The Kibble mechanism plays a prominent role in the theory of the early Universe, as an explanation of the possible formation of cosmic strings. Zurek suggested the analogous effect…

A pion decay constant in the multi-flavor Schwinger model
Jaime Fabián Nieto Castellanos, Ivan Hip, Wolfgang Bietenholz
The pion decay constant plays an important role in QCD and in Chiral Perturbation Theory. It is hardly known, however, that a corresponding constant exists in the Schwinger m…

Non-equilibrium dynamics of topological defects in the 3d O(2) model
Edgar López-Contreras, Jaime Fabián Nieto Castellanos, Elías Natanael Polanco-Euán +1
We present a study of the 3d O(2) non-linear -model on the lattice, which exhibits topological defects in the form of vortices. They tend to organize into vortex lines that bear…
