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…
Large N expansion for the 2D Dyson gas
A. Zabrodin, P. Wiegmann
We discuss the 1/N expansion of the free energy of N logarithmically interacting charges in the plane in an external field. For some particular values of the inverse temperature be…
Theta-terms in nonlinear sigma-models
A. G. Abanov, P. B. Wiegmann
We trace the origin of theta-terms in non-linear sigma-models as a nonperturbative anomaly of current algebras. The non-linear sigma-models emerge as a low energy limit of fermioni…
