Finite temperature and quench dynamics in the Transverse Field Ising Model from form factor expansions
We consider the problems of calculating the dynamical order parameter two-point function at finite temperatures and the one-point function after a quantum quench in the transverse field Ising chain. Both of these can be expressed in terms of form factor sums in the basis of physical excitations of t...
