Recent results on integrable electronic models
Alberto Anfossi, Fabrizio Dolcini, Arianna Montorsi
We review the approach of generalized permutator to produce a class of integrable quantum Hamiltonians, as well as the technique of Sutherland species (SS) to map a subclass of it…

Integrable Extended Hubbard Hamiltonians from Symmetric Group Solutions
Fabrizio Dolcini, Arianna Montorsi
We consider the most general form of extended Hubbard Hamiltonian conserving the total spin and number of electrons, and find all the 1-dimensional completely integrable models whi…
