Molecular dynamics simulation of the order-disorder phase transition in solid NaNO
Wei-Guo Yin, C. -G. Duan, W. N. Mei +3
We present molecular dynamics simulations of solid NaNO using pair potentials with the rigid-ion model. The crystal potential surface is calculated by using an \emph{a priori}…

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-…
