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…

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…

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…
