Microscopic structure of the vortex cores in granular niobium: A coherent quantum puzzle

V. S. Stolyarov, V. Neverov, A. V. Krasavin +12

When macroscopic quantum condensates -- superconductors, superfluids, cold atoms and ions, polaritons etc. -- are put in rotation, a quantum vortex lattice forms inside. In homogen…
