The Mott metal-insulator transition in the 1D Hubbard model in an external magnetic field
Holger Frahm, Temo Vekua
We study the low energy behavior of the one dimensional Hubbard model across the Mott metal-insulator phase transition in an external magnetic field. In particular we calculate ele…

Interplay between a quantum impurity and a boundary field in the SUSY t-J model
Holger Frahm, Guillaume Palacios
We study the role of bound states appearing in different formulations of the Bethe ansatz for the supersymmetric t-J model with a boundary potential and an integrable impurity. For…
