# Effect of uniaxial stress on the electronic band structure of NbP

@article{Schindler2020EffectOU, title={Effect of uniaxial stress on the electronic band structure of NbP}, author={Clemens Schindler and Jonathan Noky and Marcus Peter Schmidt and Claudia Felser and Jochen Wosnitza and Johannes Gooth}, journal={Physical Review B}, year={2020}, volume={102}, pages={035132} }

The Weyl semimetal NbP exhibits a very small Fermi surface consisting of two electron and two hole pockets, whose fourfold degeneracy in $k$ space is tied to the rotational symmetry of the underlying tetragonal crystal lattice. By applying uniaxial stress, the crystal symmetry can be reduced, which successively leads to a degeneracy lifting of the Fermi-surface pockets. This is reflected by a splitting of the Shubnikov--de Haas frequencies when the magnetic field is aligned along the $c$ axis…
