We propose an accurate tight-binding parametrization for the band structure of MoS2 monolayers near the main energy gap. We introduce a generic and straightforward derivation for the band energies equations that could be employed for other monolayer dichalcogenides. A parametrization that includes spin-orbit coupling is also provided. The proposed set of model parameters reproduce both the corr...

A dynamics of the precession coupled atomic moments in tight-binding (TB) approximation is presented. By implementing an angular penalty functional energy that captures magnetic effective fields self-consistently, motion orientation local observed faster than variation their magnitudes. This allows computation are found consistent with Heisenberg's exchange interaction, by comparison classical ...
