Coupled dimerized alternating-bond quantum spin chains in the distorted honeycomb-lattice magnet CuSbO
C. Piyakulworawat, K. Morita, Y. Fukumoto +9
We analyze powder-averaged inelastic neutron scattering and magnetization data for the distorted honeycomb compound CuSbO using a first-order dimer expansion calculation an…
Antiferromagnetic topological insulator with selectively gapped Dirac cones
A. Honma, D. Takane, S. Souma +14
Antiferromagnetic (AF) topological materials offer a fertile ground to explore a variety of quantum phenomena such as axion magnetoelectric dynamics and chiral Majorana fermions. T…
Conversion of a conventional superconductor into a topological superconductor by topological proximity effect
C. X. Trang, N. Shimamura, K. Nakayama +9
Realization of topological superconductors (TSCs) hosting Majorana fermions is a central challenge in condensed-matter physics. One approach is to use the superconducting proximity…
Direct Observation of Nonequivalent Fermi-Arc States of Opposite Surfaces in Noncentrosymmetric Weyl Semimetal NbP
S. Souma, Zhiwei Wang, H. Kotaka +9
We have performed high-resolution angle-resolved photoemission spectroscopy (ARPES) on noncentrosymmetric Weyl semimetal candidate NbP, and determined the electronic states of both…
Isotropic superconducting gaps with enhanced pairing on electron Fermi surfaces in FeTe0.55Se0.45
H. Miao, P. Richard, Y. Tanaka +17
The momentum distribution of the energy gap opening at the Fermi level of superconductors is a direct fingerprint of the pairing mechanism. While the phase diagram of the iron-base…
Two pseudogaps with different energy scales at the antinode of the high-temperature BiSrCuO superconductor using angle-resolved photoemission spectroscopy
K. Nakayama, T. Sato, Y. -M. Xu +8
We have performed high-resolution angle-resolved photoemission spectroscopy on single-layered cuprate BiSrCuO to clarify the origin of the pseudogap. By using various p…
Coupling of spin and orbital excitations in the iron-based superconductor FeSe(0.5)Te(0.5)
S. -H. Lee, Guangyong Xu, W. Ku +16
We present a combined analysis of neutron scattering and photoemission measurements on superconducting FeSe(0.5)Te(0.5). The low-energy magnetic excitations disperse only in the di…
