Light-induced switching to a Metastable Phase in a Layered Superconductor LaSrCuO (x=0.15)
Kaito Tomari, Ryusuke Matsunaga, Hiroaki Niwa +3
We investigated transient optical responses in an optimally-doped high-Tc superconductor La2-xSrxCuO4 (x=0.15) by using 800-nm optical pump and terahertz probe spectroscopy. With i…
Higgs mode in the d-wave superconductor Bi2Sr2CaCu2O8+x driven by an intense terahertz pulse
Kota Katsumi, Naoto Tsuji, Yuki I. Hamada +7
We investigated the terahertz (THz)-pulse driven nonlinear response in the d-wave cuprate superconductor Bi2Sr2CaCu2O8+x (Bi2212) using a THz pump near-infrared probe scheme in the…
Rate equation analysis on the dynamics of first-order exciton Mott transition
Fumiya Sekiguchi, Ryo Shimano
We performed a rate equation analysis on the dynamics of exciton Mott transition (EMT) with assuming a detailed balance between excitons and unbound electron-hole (e-h) pairs. Base…
Polarization-resolved terahertz third-harmonic generation in a superconductor NbN: dominance of Higgs mode beyond the BCS approximation
Ryusuke Matsunaga, Naoto Tsuji, Kazumasa Makise +3
Recent advances in time-domain terahertz (THz) spectroscopy have unveiled that resonantly-enhanced strong THz third-harmonic generation (THG) mediated by the collective Higgs ampli…
