Investigating the excitation spectrum of a single-band Hubbard model compound...
The single band Hubbard model is considerably the simplest effective model that includes both the delocalizing/hopping energy and the on-site interaction for describing strongly... -
Copy of: Investigation of magnetic transitions in a Cobalt based Brownmillerite
Brownmillerites of the form ABO2.5 constitute an interesting variant of oxygen deficient perovskites, with magnetic ions stabilized in alternate octahedral and tetrahedral...
