Optical sum rules that relate to the potential energy of strongly correlated systems
J. K. Freericks, T. P. Devereaux, M. Moraghebi +1
A class of sum rules for inelastic light scattering is developed. We show that the first moment of the non-resonant response provides information about the potential energy in stro…

Unveiling New Magnetic Phases of Undoped and Doped Manganites
Takashi Hotta, Mohammad Moraghebi, Adrian Feiguin +3
Novel ground-state spin structures in undoped and lightly-doped manganites are here investigated based on the orbital-degenerate double-exchange model, by using mean-field and nume…
