Charge ordering and magnetism in quarter-filled Hubbard-Holstein model
Sanjeev Kumar, Jeroen van den Brink
We study a two-dimensional Hubbard-Holstein model with phonons treated in the adiabatic limit. A Hartree-Fock decomposition is employed for the Hubbard term. A range of electronic…

Disorder-induced orbital ordering in doped manganites
Sanjeev Kumar, Arno P. Kampf
We study the effect of quenched disorder on the ordering of orbital and magnetic degrees of freedom in a two-dimensional, two-band double-exchange model for electrons coupled…
