Orbital ordering in LaMnO: Electron-electron versus electron-lattice interactions
Wei-Guo Yin, Dmitri Volja, Wei Ku
The relative importance of electron-lattice (e-l) and electron-electron (e-e) interactions in ordering orbitals in LaMnO is systematically examined within the LDA+ approxima…

Coexistence of gapless excitations and commensurate charge-density wave in the 2H-transition metal dichalcogenides
Ryan Barnett, Anatoli Polkovnikov, Eugene Demler +2
An unexpected feature common to 2H-transition metal dichalcogenides (2H-TMDs) is revealed with first-principles Wannier functions analysis of the electronic structure of the protot…

Electronic Mechanism for the Coexistence of Ferroelectricity and Ferromagnetism
C. D. Batista, J. E. Gubernatis, Wei-Guo Yin
We study the strong coupling limit of a two-band Hubbard Hamiltonian that also includes an inter-orbital on-site repulsive interaction . When the two bands have opposite pa…
