Mesoscopic BCS pairing in the repulsive 1d-Hubbard model
Luigi Amico, Andrea Mastellone, Andreas Osterloh
We study mesoscopic pairing in the one dimensional repulsive Hubbard model and its interplay with the BCS model in the canonical ensemble. The key tool is comparing the Bethe ansat…
Entanglement monotones and maximally entangled states in multipartite qubit systems
Andreas Osterloh, Jens Siewert
We present a method to construct entanglement measures for pure states of multipartite qubit systems. The key element of our approach is an antilinear operator that we call {\em co…
Constructing N-qubit entanglement monotones from anti-linear operators
Andreas Osterloh, Jens Siewert
We present a method to construct entanglement measures for pure states of multipartite qubit systems. The key element of our approach is an antilinear operator that we call {\em co…
Quasi-classical descendants of disordered vertex models with boundaries
Antonio Di Lorenzo, Luigi Amico, Kazuhiro Hikami +2
We study descendants of inhomogeneous vertex models with boundary reflections when the spin-spin scattering is assumed to be quasi--classical. This corresponds to consider certain…
Integrable model for interacting electrons in metallic grains
Luigi Amico, Antonio Di Lorenzo, Andreas Osterloh
We find an integrable generalization of the BCS model with non-uniform Coulomb and pairing interaction. The Hamiltonian is integrable by construction since it is a functional of co…
Fermionic long range correlations realized by particles obeying deformed statistics
Andreas Osterloh, Luigi Amico, Ulrich Eckern
Deformed exchange statistics is realized in terms of electronic operators. This is employed to rewrite Hubbard type lattice models for particles obeying deformed statistics (we ref…
