Title: Quantum oscillations and Dirac-Landau levels in Weyl superconductors,
Abstract: When magnetic field is applied to metals and semimetals quantum oscillations
appear as individual Landau levels cross the Fermi level. Quantum oscillations
generally do not occur in superconductors (SC) because magnetic field is either
expelled from the sample interior or, if strong enough, drives the material
into the normal state. In addition, elementary excitations of a superconductor
-- Bogoliubov quasiparticles -- do not carry a well defined electric charge and
therefore do not couple in a simple way to the applied magnetic field. We
predict here that in Weyl superconductors certain types of elastic strain have
the ability to induce chiral pseudo-magnetic field which can reorganize the
electronic states into Dirac-Landau levels with linear band crossings at low
energy. The resulting quantum oscillations in the quasiparticle density of
states and thermal conductivity can be experimentally observed under a bending
deformation of a thin film Weyl SC and provide new insights into this
fascinating family of materials.
