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: 10.1063/5.0211437
Abstract: The Josephson effect is a hallmark signature of the superconducting state, which, however, has been sparsely explored in non-crystalline superconducting materials. Motivated by this, we consider a Josephson junction consisting of two superconductors with a… read more here.

DOI: 10.1088/1367-2630/adaa0f
Abstract: The Josephson effect is a macroscopic quantum tunneling phenomenon in a system with superfluid property, when it is split into two parts by a barrier. Here, we examine the Josephson effect in a driven-dissipative supersolid… 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.

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.

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.
