A damping of the de Haas van Alphen oscillations in the superconducting state
Abstract
Deploying a recently developed semiclassical theory of quasiparticles in the superconducting state we study the de Haas-van Alphen effect. We find that the oscillations have the same frequency as in the normal state but their amplitude is reduced. We find an analytic formula for this damping which is due to tunnelling between semiclassical quasiparticle orbits comprising both particle-and hole-like segments. The quantitative predictions of the theory are consistent with the available data.
