In-plane and interlayer magnetoresistance in FeSe

Taichi Terashima, Shinya Uji, Hiroaki Ikeda +3

We report measurements of the in-plane and interlayer magnetoresistances of FeSe. The in-plane magnetoresistance for is positive below

Observation of Anomalous Thermal Hall Effect in a Kagome Superconductor

Hiroki Yoshida, Hikaru Takeda, Jian Yan +8

Broken time-reversal symmetry (TRS) in superconductors can induce not only spontaneous magnetization by the finite angular momentum of Cooper pairs, but also anomalous thermal Hall…

Kitaev Quantum Spin Liquids

Yuji Matsuda, Takasada Shibauchi, Hae-Young Kee

Quantum spin liquids (QSLs) represent exotic states of matter where quantum spins interact strongly yet evade long-range magnetic order down to absolute zero. Characterized by non-…

Quasiparticle interaction originating from Bogoliubov Fermi Surfaces under pressure in 18%-S substituted FeSe studied via NMR

Zhongyu Yu, Xiaoling Shen, Koya Nakamura +8

S-substituted FeSe superconductors in the tetragonal phase display several unique features among iron-based superconductors, particularly the presence of zero-energy excitations in…

Bulk excitations in ultraclean -RuCl: Quantitative evidence for Majorana dispersions in a Kitaev quantum spin liquid

Kumpei Imamura, Ryuichi Namba, Riku Ishioka +6

The spin-orbit coupled Mott insulator -RuCl has emerged as a prime candidate for realizing the Kitaev quantum spin liquid (KQSL), characterized by Majorana quasiparticles,…

Anomalous Electrical Transport in the Kagome Magnet YbFeGe

Weiliang Yao, Supeng Liu, Hodaka Kikuchi +19

Two-dimensional (2D) kagome metals offer a unique platform for exploring electron correlation phenomena derived from quantum many-body effects. Here, we report a combined study of…
