Charge carrier dynamics of FeSe thin film investigated by terahertz magneto-optical spectroscopy
We performed terahertz magneto-optical spectroscopy of FeSe thin film to elucidate the charge carrier dynamics. The measured diagonal (longitudinal) and off-diagonal (Hall) conductivity spectra areExpand

Determination of the BCS material parameters of the HIE-ISOLDE superconducting resonator
Superconducting material parameters of the Nb film coating on the Quarter-Wave Resonator (QWR) for the HIE-ISOLDE project were studied by fitting experimental results with the Mattis-Bardeen theory.Expand
Type-II thin film superconductors studied by terahertz radiation
Utilization of type-II superconductors for future practical applications such as fluxonics requires detailed knowledge of their physical properties, especially at high frequencies within the THzExpand
Quasiclassical Theory on Third-Harmonic Generation in Conventional Superconductors with Paramagnetic Impurities
We investigate the third-harmonic generation (THG) of s-wave superconductors under microwave pulse irradiation. We consider the effect of paramagnetic impurities on the THG intensity of dirtyExpand
Terahertz electrodynamics and superconducting energy gap of NbN
We have measured the transmission spectra of the conventional Bardeen-Cooper-Schrieffer (BCS) superconductor niobium nitride (NbN) thin films (Tc = 11 K) using terahertz time-domain spectroscopyExpand
Green's function approach to the non-equilibrium superconductivity near the critical line
In spite of the absent friction of super-currents, normal currents affect the superconducting condensate. The BCS approach with Bogoliubov-Valutin quasiparticles is not suited for description of theExpand
Anisotropic behaviour of transmission through thin superconducting NbN film in parallel magnetic field
Transmission of terahertz waves through a thin layer of the superconductor NbN deposited on an anisotropic R-cut sapphire substrate is studied as a function of temperature in a magnetic fieldExpand
