Kitaev interactions between j=1/2 moments in honeycomb Na2IrO3 are large and ferromagnetic: insights from ab initio quantum chemistry calculations
Vamshi M. Katukuri, S. Nishimoto, V. Yushankhai +7
NaIrO, a honeycomb 5 oxide, has been recently identified as a potential realization of the Kitaev spin lattice. The basic feature of this spin model is that for each o…

The Hubbard model in the two-pole approximation
A. Avella, F. Mancini, D. Villani +2
The two-dimensional Hubbard model is analyzed in the framework of the two-pole expansion. It is demonstrated that several theoretical approaches, when considered at their lowest le…
