19 Apr 2016 | | Abstract: | We report on the pressure evolution of the Fermi surface topology of the Weyl
semimetal NbP, probed by Shubnikov-de Haas oscillations in the
magnetoresistance combined with ab-initio calculations of the band-structure.
Although we observe a drastic effect on the amplitudes of the quantum
oscillations, the frequencies only exhibit a weak pressure dependence up to 2.8
GPa. The pressure-induce variations in the oscillation frequencies are
consistent with our band-structure calculations. Furthermore, we can relate the
changes in the amplitudes to small modifications in the shape of the Fermi
surface. Our findings evidenced the stability of the electronic band structure
of NbP and demonstrate the power of combining quantum-oscillation studies and
band-structure calculations to investigate pressure effects on the
Fermi-surface topology in Weyl semimetals. | | Source: | arXiv, 1604.5502 | | Services: | Forum | Review | PDF | Favorites | |
