Superconducting fluctuations probed by the Higgs mode in BiSrCaCuO thin films
Kota Katsumi, Zhi Zhong Li, Hélène Raffy +2
Superconducting (SC) fluctuations in cuprate superconductors have been extensively studied to gain a deep insight into preformed Cooper pairs above the SC transition temperature $T…
Higgs Mode in Superconductors
Ryo Shimano, Naoto Tsuji
When a continuous symmetry of a physical system is spontaneously broken, two types of collective modes typically emerge: the amplitude and phase modes of the order-parameter fluctu…
Light-induced nonequilibrium response of the superconducting cuprate LaSrCuO
Hiroaki Niwa, Naotaka Yoshikawa, Kaito Tomari +4
We report the dynamics of the cuprate superconductor LaSrCuO () after intense photoexcitation utilizing near-infrared (800 nm) optical pump-terahertz pr…
Charge carrier dynamics of FeSe thin film investigated by terahertz magneto-optical spectroscopy
Naotaka Yoshikawa, Masayuki Takayama, Naoki Shikama +4
We performed terahertz magneto-optical spectroscopy of FeSe thin film to elucidate the charge carrier dynamics. The measured diagonal (longitudinal) and off-diagonal (Hall) conduct…
Nonlinear optical response of collective modes in multiband superconductors assisted by nonmagnetic impurities
Yuta Murotani, Ryo Shimano
In multiband superconductors, multiple collective modes exist associated with the multiple order parameters. Oscillations of the amplitude and the relative phase of the order param…
Phase-resolved Higgs response in superconducting cuprates
Hao Chu, Min-Jae Kim, Kota Katsumi +26
In high energy physics, the Higgs field couples to gauge bosons and fermions and gives mass to their elementary excitations. Experimentally, such couplings can be inferred from the…
