TL;DR: The results suggest that the A1g superconducting symmetry is universal in iron-pnictides, in spite of the variety of gap functions.
Journal ArticleDOI

TL;DR: This work identifies a non-trivial state with a single-point Fermi node protected by cubic and time-reversal symmetries, and implies that Pr2Ir2O7 is a parent state that can be manipulated to produce other strongly correlated topological phases, such as topological Mott insulator, Weyl semimetal, and quantum spin and anomalous Hall states.
Journal ArticleDOI
Strongly spin-orbit coupled two-dimensional electron gas emerging near the surface of polar semiconductors
M. Sakano,Mohammad Saeed Bahramy,A. Katayama,Takahiro Shimojima,H. Murakawa,Yoshio Kaneko,Walid Malaeb,Shik Shin,Kanta Ono,Hiroshi Kumigashira,Ryotaro Arita,Ryotaro Arita,Naoto Nagaosa,Harold Y. Hwang,Y. Tokura,Kyoko Ishizaka,Kyoko Ishizaka +16 more
TL;DR: Two-dimensional highly spin-polarized electron accumulation layers commonly appearing near the surface of n-type polar semiconductors BiTeX (X=I, Br, and Cl) are investigated by angular-resolved photoemission spectroscopy and show giant Rashba-type spin splitting.
Journal ArticleDOI
Spin texture in type-II Weyl semimetal WTe 2

TL;DR: In this paper, the spin and angle-resolved photoemission spectroscopy (SARPES) was used to determine the band structure and spin texture of a type-II Weyl semimetal.
Journal ArticleDOI
Point nodes persisting far beyond Tc in Bi2212
Takeshi Kondo,Walid Malaeb,Yukiaki Ishida,Takao Sasagawa,Hideki Sakamoto,Tsunehiro Takeuchi,Takami Tohyama,Shik Shin +7 more
TL;DR: It is revealed that the superconductivity occurs when the pair-breaking rate is suppressed smaller than the single-particle scattering rate on cooling, which governs the value of Tc in cuprates.
