Josephson Current and Noise at a Superconductor/Quantum-Spin-Hall-Insulator/Superconductor Junction
We study junctions between superconductors mediated by the edge states of a quantum-spin-Hall insulator. We show that such junctions exhibit a fractional Josephson effect, in which the current phase relation has a 4π rather than a 2π periodicity. This effect is a consequence of the conservation of fermion parity—the number of electron mod 2—in a superconducting junction and is closely related t...
متن کاملCurrent-Induced Chiral Phase Transition in a Josephson-Junction Array
It is predicted that the fully frustrated Josephson-junction array on a square lattice with alternating columns of junctions having a reduced critical current Iweak = μI0(with μ < 1 and I0 the critical current of all other junctions) in certain range of μ will under increasing of the external current first change from the state with zero chirality to the state with nonzero one at the lower crit...
متن کاملTheory of the Josephson effect in superconductor / ferromagnet / superconductor junctions
To reveal the influence of the exchange interaction on the Josephson effect, the d.c. Josephson current in unconventional-superconductor / ferromagnet / unconventional-superconductor junctions is studied. When the two superconductors have d-wave symmetry, the Josephson current is drastically suppressed with the increase of the exchange interaction. On the other hand, when the two superconductor...
متن کاملThe Superconductor-to-Insulator Transition in Resistively-Shunted Josephson-Junction Arrays
This essay describes the, analytical theory, experimental observations and potential applications of superconductor‐to‐insulator quantum phase transitions in arrays of resistively‐shunted Josephson junctions and superconducting islands dissipatively‐coupled to an external source of single‐particle excitations.
متن کاملQuasiclassical Green’s function theory of the Josephson effect in chiral p-wave superconductor/diffusive normal metal/chiral p-wave superconductor junctions
We study the Josephson effect in chiral p-wave superconductor/diffusive normal metal DN /chiral p-wave superconductor CP/DN/CP junctions using quasiclassical Green’s function formalism with proper boundary conditions. The px+ ipy-wave symmetry of superconducting order parameter is chosen which is believed to be the pairing state in Sr2RuO4. We show that the superconducting pair amplitude induce...
