DOI: 10.1007/s10909-018-1849-8
Abstract: In this review, we summarize the achievement of the physics of surface Andreev bound states (SABS) up to now. The route of this activity has started from the physics of SABS of unconventional superconductors where… read more here.

DOI: 10.1088/1367-2630/abe15d
Abstract: Pair density waves, identified by Cooper pairs with finite center-of-mass momentum, have recently been observed in copper oxide based high T c superconductors (cuprates). A charge density modulation or wave is also ubiquitously found in… read more here.

DOI: 10.1103/physrevb.100.115433
Abstract: We investigate odd-frequency superconducting correlations in normal-superconductor (NS) and short superconductor-normal-superconductor (SNS) junctions with the S region described by the Kitaev model of spinless fermions in one dimension. We demonstrate that, in both the trivial… read more here.

DOI: 10.1103/physrevb.102.125429
Abstract: We study the magnon-mediated pairing between fermions on the surface of a topological insulator (TI) coupled to a ferromagnetic insulator with a tilted mean field magnetization. Tilting the magnetization towards the interfacial plane reduces the… read more here.

DOI: 10.1103/physrevb.102.184506
Abstract: We demonstrate that $\mathrm{Sr}\mathrm{Ti}{\mathrm{O}}_{3}$ can be a platform for observing the bulk odd-frequency superconducting state owing to its multiorbital/multiband nature. We consider a three-orbital tight-binding model for $\mathrm{Sr}\mathrm{Ti}{\mathrm{O}}_{3}$ in the vicinity of a ferroelectric critical… read more here.

DOI: 10.1103/physrevb.104.054519
Abstract: We predict for perhaps the first time, the occurrence of odd frequency equal spin-triplet correlations at a normal metal-superconductor junction. This result is important because the existence of equal spin-triplet correlations is associated with the… read more here.

Abstract: We show that all the singlet even-frequency, singlet odd-frequency, triplet even-frequency and triplet odd-frequency pairings, and together with the corresponding order parameters (gaps) can be realized in InSb (110) spin-orbit-coupled quantum well in proximity to… read more here.

DOI: 10.1103/physrevb.97.134523
Abstract: Topological superconductors give rise to unconventional superconductivity, which is mainly characterized by the symmetry of the superconducting pairing amplitude. However, since the symmetry of the superconducting pairing amplitude is not directly observable, its experimental identification… read more here.

Abstract: At an interface between a topological insulator (TI) and a conventional superconductor (SC), superconductivity has been predicted to change dramatically and exhibit novel correlations. In particular, the induced superconductivity by an s-wave SC in a… read more here.
