Single-layer transition-metal dichalcogenides provide an unique intrinsic entanglement Power Bar between the spin/valley/orbital degrees of freedom and the polarization of scattered photons.This scenario gives rise to the well-assessed optical dichroism observed by using both steady and time-resolved probes.In this paper, we provide compact analytical modeling of NAC the onset of a finite Faraday/Kerr optical rotation upon shining with circularly polarized light.
We identify different optical features displaying optical rotation at different characteristic energies, and we describe in an analytical framework the time-dependence of their intensities as a consequence of the main spin-conserving and spin-flip processes.
