Generalization of spectral bulk-boundary correspondence
Shun Tamura, Shintaro Hoshino, Yukio Tanaka
The bulk-boundary correspondence in one dimension asserts that the physical quantities defined in the bulk and at the edge are connected, as well established in the argument for el…
Impact of impurity scattering on odd-frequency spin-triplet pairing near the edge of the Kitaev chain
Sparsh Mishra, Shun Tamura, Akito Kobayashi +1
We study a Kitaev chain model, which is the simplest model of topological superconductors hosting Majorana fermion, appearing as a zero-energy state at the edge. We analytically ca…
Bulk odd-frequency pairing in the superconducting Su-Schrieffer-Heeger model
Shun Tamura, Sho Nakosai, Annica M. Black-Schaffer +2
The Su-Schrieffer-Heeger model describes fermions that hop on a one-dimensional chain with staggered hopping amplitude, where the unit cell contains two sites, or two sublattices.…
Theory of proximity effect in two-dimensional unconventional superconductor with Rashba spin-orbit interaction
Shun Tamura, Yukio Tanaka
We study the anomalous proximity effect in diffusive normal metal (DN)/unconventional superconductor junctions, where the local density of states (LDOS) in the DN has a zero-energy…
Theory of surface Andreev bound states and tunneling spectroscopy in three-dimensional chiral superconductors
Shun Tamura, Shingo Kobayashi, Lu Bo +1
We study the surface Andreev bound states (SABSs) and quasiparticle tunneling spectroscopy of three-dimensional (3D) chiral superconductor by changing the surface (interface) misor…
