CMT Seminar - Arun Paramekanti (University of Toronto) "Pseudo-Landau levels in strained nodal superconductors"

    Theory and experiments on graphene have shown that strain can be tailored to induce pseudo-vector potentials and pseudo-magnetic fields as large as 300 Tesla for the low energy Dirac fermions.  Motivated by this, and related theoretical work on other Dirac systems, we consider the impact of strain on nodal d-wave superconductors.  We theoretically show that suitable inhomogeneous strain fields can lead to pseudo-Landau levels for the Bogolinubov quasiparticles, with detectable signatures in STM experiments and possibly THz spectroscopy
