Finite-temperature lineshapes in gapped quantum spin chains

We consider the finite-temperature dynamical susceptibility χ (ω,q,T) of gapped quantum spin chains such as the integer spin Heisenberg and transverse field Ising models. At zero temperature χ in these models is dominated by a delta-function line arising from the coherent propagation of single-parti...
