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…
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…
Exact solution of generalized Schulz-Shastry type models
A. Osterloh, L. Amico, U. Eckern
A class of integrable one-dimensional models presented by Shastry and Schulz is consequently extended to the whole class of one-dimensional Hubbard- or XXZ-type models with correla…
Bethe Ansatz solution of a new class of Hubbard-type models
A. Osterloh, L. Amico, U. Eckern
We define one-dimensional particles with generalized exchange statistics. The exact solution of a Hubbard-type Hamiltonian constructed with such particles is achieved using the Coo…
One-Dimensional XXZ Model for Particles Obeying Fractional Statistics
Luigi Amico, Andreas Osterloh, Ulrich Eckern
We define one-dimensional particles as non-abelian representations of the symmetric group . The exact solution of an type Hamiltonian built up with such particles is ach…
