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…

Spectral functions of the Falicov-Kimball model with electronic ferroelectricity
Wei-Guo Yin, W. N. Mei, Chun-Gang Duan +2
We calculate the angular resolved photoemission spectrum of the Falicov-Kimball model with electronic ferroelectricity where - and -electrons have different hoppings. In mix-…
