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

Dichotomy of saddle points in energy bands of monolayer NbSe 2
Se Joong Kim,Young-Woo Son +1 more
TL;DR: In this paper, the authors theoretically show that two distinctive spin textures manifest themselves around saddle points in energy bands of monolayer layers under external gate potentials, and establish distinct effective Rashba Hamiltonians for each saddle point, realizing the unique spin textures depending on their momentum.

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.
