Dynamics in the Ising field theory after a quantum quench
We study the real-time dynamics of the order parameter 〈σ(t) 〉 in the Ising field theory after a quench in the fermion mass, which corresponds to a quench in the transverse field of the corresponding transverse field Ising chain. We focus on quenches within the ordered phase. The long-time behaviour...
