Tachyonic quench in a free bosonic field theory
Sebastian Montes, Javier Rodríguez-Laguna, Germán Sierra
We present a characterization of a bosonic field theory driven by a free (Gaussian) tachyonic Hamiltonian. This regime is obtained from a theory describing two coupled bosonic fiel…

Phase diagram and quench dynamics of the Cluster-XY spin chain
Sebastian Montes, Alioscia Hamma
We study the complete phase space and the quench dynamics of an exactly solvable spin chain, the cluster-XY model. In this chain, the cluster term and the XY couplings compete to g…
