Show affiliationsSolving the Gross–Pitaevskii-type equation it is shown that the magneto-oscillations observed in the superconducting state of a few underdoped cuprates originate in the quantum interference of the vortex lattice with nanoscale crystal lattice modulations of the order parameter as revealed by scanning tunneling microscopy. The commensuration of the vortex lattice and crystal lattice have 1/B1/2 periodicity, rather than the 1/B periodicity of conventional normal state magneto-oscillations. Experimental conditions allowing for a resolution of quantum magneto-oscillations of two different types are outlined.
