  • We theoretically study the vortex matter structure in low-dimensional systems with superconducting order induced by proximity to a bulk superconductor. We analyze the effects of microscopic coupling mechanisms between the two systems and the effects of possible mismatch in the band structures of these materials on the energy spectrum of vortex-core electrons. The unusual structure of vortex cores is discussed in the context of recent tunneling microscopy/spectroscopy experiments.
  • It is shown that the parity-violated ground state of two-dimensional strongly correlated electronic systems (commensurate flux state) provides a physical realization of the anyon mechanism of superconductivity. The electromagnetic response of the commensurate flux state is calculated. It is found that the superconducting ground state is accompanied by the {ital restoration} of parity and time-reversal symmetry: the parity-violation signal is very small at low energies and momentum, and vanishes in the static limit as well as in the uniform limit.

  • Here, we find a giant inverse proximity effect that arises in small low-dimensional superconductor-normal-superconductor (S/N/S) junctions, where a proximity coherence length is larger than the coherence length of a source superconductor, due to a huge backaction exerted by normal conductors on the proximity superconducting regions. Furthermore, the inverse proximity develops even in case where dimensions of the normal parts are smaller than the proximity coherence length and significantly suppresses superconducting characteristics of the entire system, including critical current, well below those for the usual S/N/S structures.
