The XXZ model with anti-periodic twisted boundary conditions
Sönke Niekamp, Tobias Wirth, Holger Frahm
We derive functional equations for the eigenvalues of the XXZ model subject to anti-diagonal twisted boundary conditions by means of fusion of transfer matrices and by Sklyanin's m…

Renormalized Thermal Entropy in Field Theory
Sergio Cacciatori, Fabio Costa, Federico Piazza
Standard entropy calculations in quantum field theory, when applied to a subsystem of definite volume, exhibit area-dependent UV divergences that make a thermodynamic interpretatio…
