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…
