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…

Photoemission spectra of a two-dimensional S=1/2 quantum antiferromagnet in magnetic fields: a theoretical study
Wei-Guo Yin, W. N. Mei
We calculate the angular resolved photoemission spectra (ARPES) of a spin-1/2 Heisenberg antiferromagnet as a function of magnetic fields using both the exact diagonalization metho…
