Twisted Hubbard Model for Sr2IrO4: Magnetism and Possible High Temperature Superconductivity
Twisted Hubbard Model for Sr2IrO4 Magnetism Possible High Temperature Superconductivity
2010/11/23
Sr2IrO4 has been suggested as a Mott insulator from a single Jeff = 1/2 band, similar to the
cuprates. However this picture is complicated by the measured large magnetic anisotropy and
ferromagnetis...
Orbital Order, Metal Insulator Transition, and Magnetoresistance-Effect in the two-orbital Hubbard model
Orbital Order Metal Insulator Transition Magnetoresistance-Effect
2010/11/19
We study the effects of temperature and magnetic field on a two-orbital Hubbard model within
dynamical mean field theory. We focus on the quarter filled system, which is a special point in the phase ...

In his Comment [see preceding Comment, Phys. Rev. A 82, 037601 (2010)] on the paper by Roux [Phys.Rev. A 79, 021608(R) (2009)], Rigol argued that the energy distribution after a quench is not related ...
