Separation of Variables in the open XXX chain
H. Frahm, A. Seel, T. Wirth
We apply the Sklyanin method of separation of variables to the reflection algebra underlying the open spin-1/2 XXX chain with non-diagonal boundary fields. The spectral problem can…
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…
Correlation functions of one-dimensional Bose-Fermi mixtures
Holger Frahm, Guillaume Palacios
We calculate the asymptotic behaviour of correlation functions as a function of the microscopic parameters for a Bose-Fermi mixture with repulsive interaction in one dimension. For…
New representations of the Hecke algebra and algebraic Bethe Ansatz for an integrable generalized spin ladder
Huan-Qiang Zhou, Holger Frahm, Mark D. Gould
This paper has been withdrawn by the authors, due an error in Bethe Ansatz equations (16).
