Coherent Dirac plasmons in topological insulators
Richarj Mondal, Akira Arai, Yuta Saito +4
We explore the ultrafast reflectivity response from photo-generated coupled phonon-surface Dirac plasmons in SbTe topological insulators several quintuple layers thick. The…
Photoinduced Fano-resonance of coherent phonons in zinc
Muneaki Hase, Jure Demsar, Masahiro Kitajima
Utilizing femtosecond optical pump-probe technique, we have studied transient Fano-resonance in zinc. At high excitation levels the Fourier spectrum of the coherent E phonon…
Ultrafast dynamics of coherent optical phonons and nonequilibrium electrons in transition metals
Muneaki Hase, Kunie Ishioka, Jure Demsar +2
The femtosecond optical pump-probe technique was used to study dynamics of photoexcited electrons and coherent optical phonons in transition metals Zn and Cd as a function of tempe…
Spin-phonon coupled modes in the incommensurate phases of doped CuGeO
K. Takehana, T. Takamasu, M. Hase +3
The doping effect of the folded phonon mode at 98 cm was investigated on the Si-doped CuGeO by magneto-optical measurements in far-infrared (FIR) region under high magne…
Far-Infrared Spectroscopy in Spin-Peierls Compound CuGeO_3 under High Magnetic Fields
K. Takehana, T. Takamasu, M. Hase +2
Polarized far-infrared (FIR) spectroscopic measurements and FIR magneto-optical studies were performed on the inorganic spin-Peierls compound CuGeO_3. An absorption line, which was…
