Universal Magnetoresistance Scaling in Layered Pd-based Multiband Metals Beyond Compensated Semimetal Regime
Kenjiro Okawa, Takao Sasagawa
We systematically investigated the magnetoresistance ratio (MR) of single-crystalline, nonmagnetic layered Pd-based metals, including centrosymmetric PdTe2, PdPb2, and beta-PdBi2 a…
Direct observation of the surface superconducting gap in the topological superconductor candidate β-PdBi2
Akifumi Mine, Takeshi Suzuki, Yigui Zhong +7
β-PdBi2 is one of the candidates for topological superconductors with a superconducting (SC) transition temperature (Tc) of 5.3 K, in which parity mixing of spin singlet and spin t…
A general route to form topologically-protected surface and bulk Dirac fermions along high-symmetry lines
O. J. Clark, F. Mazzola, I. Marković +11
The band inversions that generate the topologically non-trivial band gaps of topological insulators and the isolated Dirac touching points of three-dimensional Dirac semimetals gen…
Fermiology and Superconductivity of Topological Surface States in PdTe
O. J. Clark, M. J. Neat, K. Okawa +15
We study the low-energy surface electronic structure of the transition-metal dichalcogenide superconductor PdTe by spin- and angle-resolved photoemission, scanning tunneling mi…
Full-gap superconductivity in spin-polarized surface states of topological semimetal -PdBi
K. Iwaya, Y. Kohsaka, K. Okawa +4
A bulk superconductor possessing a topological surface state at the Fermi level is a promising system to realize long-sought topological superconductivity. Although several candida…
Probing the superconducting gap symmetry of -PdBi: A penetration depth study
S. Mitra, K. Okawa, S. Kunniniyil Sudheesh +3
We report measurements of the in-plane London penetration depth in single crystals of the -PdBi superconductor --- the -phase counterpart of the putative topologica…
Ubiquitous formation of bulk Dirac cones and topological surface states from a single orbital manifold in transition-metal dichalcogenides
M. S. Bahramy, O. J. Clark, B. -J. Yang +23
Transition-metal dichalcogenides (TMDs) are renowned for their rich and varied properties. They range from metals and superconductors to strongly spin-orbit-coupled semiconductors…
Topologically protected surface states in a centrosymmetric superconductor beta-PdBi2
M. Sakano, K. Okawa, M. Kanou +4
The topological aspects of electrons in solids emerge in realistic matters as represented by topological insulators. They are expected to show a variety of new magneto-electric phe…
