High-field fate of the Kitaev quantum spin liquid in -RuCl
K. Imamura, R. Ohno, Y. C. Tsuzuki +15
Kitaev quantum spin liquids (KQSLs) host fractionalized excitations described by itinerant Majorana quasiparticles and gapped fluxes (visons), providing a platform for emerge…
Impact of charge-density-wave pattern on the superconducting gap in V-based kagome superconductors
T. Nagashima, K. Ishihara, Y. Yamakawa +12
Kagome metals VSb ( K, Rb, Cs) provide a compelling platform to explore the interplay between superconductivity (SC) and charge-density-wave (CDW) orders. While dist…
Magnetothermal transport in ultraclean single crystals of Kitaev magnet -RuCl
Y. Xing, R. Namba, K. Imamura +7
The layered honeycomb magnet -RuCl has emerged as a promising candidate for realizing a Kitaev quantum spin liquid. Previous studies have reported oscillation-like anomalie…
Impact of tiny Fermi pockets with extremely high mobility on the Hall anomaly in the kagome metal CsVSb
S. Liu, M. Roppongi, M. Kimata +8
The kagome metal CsVSb exhibits an unusual charge-density-wave (CDW) order, where the emergence of loop current order that breaks time-reversal symmetry (TRS) has been prop…
Field-Angle-Resolved Specific Heat in NaCoTeO: Evidence against Kitaev Quantum Spin Liquid
Shengjie Fang, Kumpei Imamura, Yuta Mizukami +4
Kitaev quantum spin liquids (KSLs) in layered honeycomb magnets are known to host Majorana quasiparticles, whose excitations depend strongly on the direction of the applied magneti…
Topology meets time-reversal symmetry breaking in FeSeTe superconductor
M. Roppongi, Y. Cai, K. Ogawa +21
Time-reversal symmetry breaking (TRSB) in magnetic topological insulators induces a Dirac gap in the topological surface state (TSS), leading to exotic phenomena such as the quantu…
