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…

Dressed energy of the XXZ chain in the complex plane
Saskia Faulmann, Frank Göhmann, Karol K. Kozlowski
We consider the dressed energy of the XXZ chain in the massless antiferromagnetic parameter regime at and at finite magnetic field. This function is define…
