Characteristic electronic structure and its doping evolution in lightly-doped to underdoped YBa2Cu3Oy
H. Yagi, T. Yoshida, A. Fujimori +15
We have performed an angle resolved photoemission spectroscopy (ARPES) study of lightly-doped to underdoped YBa2Cu3Oy (YBCO) untwinned single crystals and a core-level x-ray photoe…
Spin-Rotation Symmetry Breaking in the Superconducting State of CuxBi2Se3
K. Matano, M. Kriener, K. Segawa +2
Spontaneous symmetry breaking is an important concept for understanding physics ranging from the elementary particles to states of matter. For example, the superconducting state br…
On infrared pseudogap in cuprate and pnictide high-temperature superconductors
S. J. Moon, Y. S. Lee, A. A. Schafgans +15
We investigate infrared manifestations of the pseudogap in the prototypical cuprate and pnictide superconductors: YBa2Cu3Oy and BaFe2As2 (Ba122) systems. We find remarkable similar…
Origin of multiple skyrmion phases in EuAl4
Y. Arai, K. Nakayama, A. Honma +6
The Dzyaloshinskii-Moriya (DM) interaction has been considered essential for skyrmion formation, however, the discovery of skyrmion lattices (SkLs) in nominally centrosymmetric mat…
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…
