Interacting Dirac fields in an expanding universe: dynamical condensates and particle production
Carlos Fulgado-Claudio, Pablo Sala, Daniel González-Cuadra +1
The phenomenon of particle production for quantum field theories in curved spacetimes is crucial to understand the large-scale structure of a universe from an inflationary epoch. I…

Gaussian states for the variational study of (1+1)-dimensional lattice gauge models
P. Sala, T. Shi, S. Kühn +3
We introduce a variational ansatz based on Gaussian states for (1+1)-dimensional lattice gauge models. To this end we identify a set of unitary transformations which decouple the g…

Variational study of U(1) and SU(2) lattice gauge theories with Gaussian states in 1+1 dimensions
P. Sala, T. Shi, S. Kühn +3
We introduce a method to investigate the static and dynamic properties of both Abelian and non-Abelian lattice gauge models in 1+1 dimensions. Specifically, we identify a set of tr…
