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…
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 anomalies…
Lifting of gap nodes by disorder in ultranodal superconductor candidate FeSe1-xSx
T. Nagashima, K. Ishihara, K. Imamura +8
The observation of time-reversal symmetry breaking and large residual density of states in tetragonal FeSeS suggests a novel type of ultranodal superconducting state wi…
Microwave Hall measurements using a circularly polarized dielectric cavity
M. Roppongi, T. Arakawa, Y. Yoshino +6
We have developed a circularly polarized dielectric rutile (TiO) cavity with a high quality-factor that can generate circularly polarized microwaves from two orthogonal linearl…
Two-step growth of high-quality single crystals of the Kitaev magnet -RuCl
R. Namba, K. Imamura, R. Ishioka +14
The layered honeycomb magnet -RuCl is the most promising candidate for a Kitaev quantum spin liquid (KQSL) that can host charge-neutral Majorana fermions. Recent studies hav…
