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…

Entanglement in a second order quantum phase transition
J. Vidal, G. Palacios, R. Mosseri
We consider a system of mutually interacting spin 1/2 embedded in a transverse magnetic field which undergo a second order quantum phase transition. We analyze the entanglement pro…
