Integrable spin-boson interaction in the Tavis-Cummings model from a generic boundary twist
Luigi Amico, Kazuhiro Hikami
We construct models describing interaction between a spin and a single bosonic mode using a quantum inverse scattering procedure. The boundary conditions are generically twiste…

Out of equilibrium correlation functions of quantum anisotropic XY models: one-particle excitations
Luigi Amico, Andreas Osterloh
We calculate exactly matrix elements between states that are not eigenstates of the quantum XY model for general anisotropy. Such quantities therefore describe non equilibrium prop…
