Sweeping reciprocal vortex lattice across the Fermi surface: A new
magnetoquantum oscillations effect in the superconducting state
   [PDF]

T. Maniv, V. Zhuravlev
It is shown that coherent scatterings by an ordered vortex lattice are critically enhanced for quasi particles moving in cyclotron orbits on the Fermi surface through vortex core regions, thus generating significant quasi-periodic oscillating contributions to the SC free energy as a function of the inverse magnetic field. The mean frequency of the oscillation provides a fingerprint of the vortex lattice geometry. Vortex-lattice disorder, tends to suppress this oscillatory component.
