Query: Effect of uniaxial stress on the electronic band structure of NbP   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 of the tetragonal lattice. In this
study, we present the measurement of Shubnikov-de Haas oscillations of
single-crystalline NbP samples under uniaxial tension, combined with
state-of-the-art calculations of the electronic band structure. Our results
show qualitative agreement between calculated and experimentally determined
Shubnikov-de Haas frequencies, demonstrating the robustness of the
band-structure calculations upon introducing strain. Furthermore, we predict a
significant shift of the Weyl points with increasing uniaxial tension, allowing
for an effective tuning to the Fermi level at only 0.8% of strain along the $a$
axis.
