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…

Loop equations for generalised eigenvalue models
Edoardo Vescovi, Konstantin Zarembo
We derive the loop equation for the 1-matrix model with generic difference-type measure for eigenvalues and develop a recursive algebraic framework for solving it to an arbitrary o…
