DOI: 10.1002/ctpp.202300014
Abstract: The Josephson effect of inter-layer s-wave pairing in a double layer of two chiral metals is considered. We employ the duality relation between electron-electron and electron-hole double layers to discuss the zero-energy eigenmodes at a… read more here.

DOI: 10.1007/s10948-021-05905-y
Abstract: Although the standard theory of superconductivity based on the BCS theory is a successful one, several experimental results indicate the necessity for a fundamental revision. We argue that the revision is on the origin of… read more here.

DOI: 10.1038/s42005-018-0100-x
Abstract: Topological Josephson junctions designed on the surface of a 3D-topological insulator harbor Majorana bound states among a continuum of conventional Andreev bound states. The distinct feature of these Majorana bound states lies in the 4π-periodicity… read more here.

DOI: 10.1103/physrevb.104.054521
Abstract: It is widely believed that superconducting junctions involving topological insulators and hosting Majorana-like bound states may exhibit unusual ”fractional” (4π-periodic) ac Josephson effect. Accordingly, ”fractional” Shapiro steps on the current-voltage characteristics of such junctions are… read more here.

DOI: 10.1103/physrevb.95.174518
Abstract: We study Josephson currents between s-wave/spin-triplet superconductor junctions by taking into account details of the band structures in Sr2RuO4, such as three conduction bands and spin-orbit interactions in the bulk and at the interface. We… read more here.

Abstract: We study the Josephson effect in a trijunction formed by two topological superconductor (TS) wires and a conventional $s$-wave superconductor. Using a boundary Green's function formalism, analytical results for the current-phase relation are obtained in… read more here.

DOI: 10.1103/physrevb.99.125153
Abstract: In topological insulator edges, the duality between the Zeeman field orientation and the proximitized superconducting phase has been recently exploited to predict a magneto-Josephson effect with a 4$\pi$ periodicity. We revisit this latter Josephson effect… read more here.

DOI: 10.1103/physrevlett.130.220403
Abstract: Close to the demixing transition, the degree of freedom associated to relative density fluctuations of a two-component Bose-Einstein condensate is described by a non-dissipative Landau-Lifshitz equation. In the quasi one-dimensional weakly immiscible case, this mapping… read more here.

DOI: 10.12693/aphyspola.133.632
Abstract: We study the Josephson effect in graphene based junctions where superconductivity in graphene is induced by the proximity effect from external substrate materials. The electronic properties of the junction is described by the Dirac-Bogoliubov-de-Gennes equations.… read more here.
