TLDR
In this paper, it was shown that spin polarization can also be achieved without the need for magnetism by using the unique crystal symmetry of tungsten selenide, which creates a Zeeman-like effect when a monolayer of the material is exposed to an external electric field.Abstract:
A magnetic field can lift the spin degeneracy of electrons. This Zeeman effect is an important route to generating the spin polarization required for spintronics. It is now shown that such polarization can also be achieved without the need for magnetism. The unique crystal symmetry of tungsten selenide creates a Zeeman-like effect when a monolayer of the material is exposed to an external electric field.read more

Intravalley scattering probed by excitation energy dependence of valley polarization in monolayer MoS2
TL;DR: In this paper, the authors investigated the intravalley scattering mediated by phonon from B exciton to A exciton in the same valley and found that the recovered valley polarization originates from the intra-valley intra-exciton scattering.

Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.
