Fractional ac Josephson effect in unconventional superconductors
Hyok-Jon Kwon, K. Sengupta, Victor M. Yakovenko
For certain orientations of Josephson junctions between two p_x-wave or two d-wave superconductors, the subgap Andreev bound states produce a 4pi-periodic relation between the Jose…
Fractional ac Josephson effect in p- and d-wave superconductors
Hyok-Jon Kwon, K. Sengupta, Victor M. Yakovenko
For certain orientations of Josephson junctions between two p_x-wave or two d-wave superconductors, the subgap Andreev bound states produce a 4pi-periodic relation between the Jose…
Spontaneous formation of a pi soliton in a superconducting wire with an odd number of electrons
Hyok-Jon Kwon, Victor M. Yakovenko
We consider a one-dimensional superconducting wire where the total number of electrons can be controlled in the Coulomb blockade regime. We predict that a pi soliton (kink) will sp…
How to detect edge electron states in (TMTSF)2X and Sr2RuO4 experimentally
Hyok-Jon Kwon, Victor M. Yakovenko, K. Sengupta
We discuss a number of experiments that could detect the electron edge states in the organic quasi-one-dimensional conductors (TMTSF)2X and the inorganic quasi-two-dimensional pero…
Edge states and determination of pairing symmetry in superconducting Sr2RuO4
K. Sengupta, Hyok-Jon Kwon, Victor M. Yakovenko
We calculate the energy dispersion of the surface Andreev states and their contribution to tunneling conductance for the order parameters with horizontal and vertical lines of node…
Dual proximity effect near superconductor-insulator transition
Hyok-Jon Kwon
We show that quantum vortex-loop proliferation may be one possible explanation of the super-long-range proximity effect observed in an insulating underdoped cuprate, using the dual…
