Thermal form-factor expansion of the dynamical two-point functions of local operators in integrable quantum chains
Frank Göhmann, Karol K. Kozlowski, Mikhail D. Minin
Evaluating a lattice path integral in terms of spectral data and matrix elements pertaining to a suitably defined quantum transfer matrix, we derive form-factor series expansions f…

Low-temperature spectrum of the quantum transfer matrix of the XXZ chain in the massless regime
Saskia Faulmann, Frank Göhmann, Karol K. Kozlowski
The free energy per lattice site of a quantum spin chain in the thermodynamic limit is determined by a single `dominant' Eigenvalue of an associated quantum transfer matrix in the…
