Nonreciprocal Terahertz Second Harmonic Generation in Superconducting NbN under Supercurrent Injection
Sachiko Nakamura, Kota Katsumi, Hirotaka Terai +1
Giant second-harmonic generation (SHG) in the terahertz (THz) frequency range is observed in a thin film of an s-wave superconductor NbN, where the time-reversal (-) a…

Specific heat, thermal conductivity, and magnetic susceptibility of cyanate ester resins --- An alternative to commonly used epoxy resins
Sachiko Nakamura, Takenori Fujii, Shoji Matsukawa +2
In low temperature experiments, resins have many applications as glues or thermal and electrical insulators. Cyanate ester resins (CEs) are a high-temperature compatible thermoset…

Infrared activation of the Higgs mode by supercurrent injection in superconducting NbN
Sachiko Nakamura, Yudai Iida, Yuta Murotani +3
Higgs mode in superconductors, i.e. the collective amplitude mode of the order parameter does not associate with charge nor spin fluctuations, therefore it does not couple to the e…
