DOI: 10.1007/jhep08(2019)047
Abstract: Abstract In analytic descriptions of quantum quenches, the overlaps between the initial pre-quench state and the eigenstates of the time evolving Hamiltonian are crucial ingredients. We construct perturbative expansions of these overlaps in quantum field… read more here.
