Finite-gap potentials as a semiclassical limit of the thermodynamic Bethe Ansatz
Valdemar Melin, Paul Wiegmann, Konstantin Zarembo
We show that the semiclassical limit of thermodynamic Bethe Ansatz equations naturally reconstructs the algebro-geometric spectra of finite-gap periodic potentials. This correspond…

Peierls Transition in Gross-Neveu Model from Bethe Ansatz
Valdemar Melin, Yuta Sekiguchi, Paul Wiegmann +1
The two-dimensional Gross-Neveu model is anticipated to undergo a crystalline phase transition at high baryon charge densities. This conclusion is drawn from the mean-field approxi…
