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…

The BCS wave function, matrix product states, and the Ising conformal field theory
Sebastian Montes, Javier Rodríguez-Laguna, Germán Sierra
We present a characterization of the many-body lattice wave functions obtained from the conformal blocks (CBs) of the Ising conformal field theory (CFT). The formalism is interpret…
