Sudden interaction quench in the quantum sine-Gordon model
J. Sabio, S. Kehrein
We study a sudden interaction quench in the weak-coupling regime of the quantum sine-Gordon model. The real time dynamics of the bosonic mode occupation numbers is calculated using…

Two-body problem in graphene
J. Sabio, F. Sols, F. Guinea
We study the problem of two Dirac particles interacting through non-relativistic potentials and confined to a two-dimensional sheet, which is the relevant case for graphene layers.…

Variational approach to the Caldeira-Leggett model
Javier Sabio, Fernando Sols
We apply the displaced-oscillator variational ansatz to the Caldeira-Leggett model for a quantum particle in a one-dimensional box described by a tight-binding chain. We focus on t…
