Terahertz field-induced nonlinear coupling of two magnon modes in an antiferromagnet
Zhuquan Zhang, Frank Y. Gao, Jonathan B. Curtis +9
Magnons are quantized collective spin-wave excitations in magnetically ordered materials. Revealing their interactions among these collective modes is crucial for the understanding…
Spin canting in nonlinear terahertz magnon dynamics revealed by magnetorefractive probing in orthoferrite
Takayuki Kurihara, Motoaki Bamba, Hiroshi Watanabe +2
We excite the spin precession in rare-earth orthoferrite YFeO3 by the magnetic field of intense terahertz pulse and probe its dynamics by transient absorption change in the near in…
Ultrafast photoluminescence in metals: Theory and its application to silver
Shota Ono, Tohru Suemoto
We study the transient photoluminescence (PL) of photoexcited metals by solving the Boltzmann equation considering the effects of electron-electron (e-e) and electron-phonon (e-ph)…
Two-dimensional terahertz magnetic resonance spectroscopy of collective spin waves
Jian Lu, Xian Li, Harold Y. Hwang +4
Nonlinear manipulation of nuclear and electron spins is the basis for all advanced methods in magnetic resonance including multidimensional nuclear magnetic and electron spin reson…
Nonlinear Photoluminescence Properties of Trions in Hole-doped Single-walled Carbon Nanotubes
Naoto Akizuki, Munechiyo Iwamura, Shinichiro Mouri +7
We studied the excitation density dependence of photoluminescence (PL) spectra of excitons and trions (charged excitons) in hole-doped single-walled carbon nanotubes. We found that…
Mechanism of enhanced optical second-harmonic generation in the conducting pyrochlore-type PbIrO oxide compound
Yasuyuki Hirata, Makoto Nakajima, Yusuke Nomura +8
The structural, electronic, and optical properties of pyrochlore-type PbIrOO', which is a metal without spatial inversion symmetry at room temperature, w…
Non-thermal hot electrons ultrafastly generating hot optical phonons in graphite
Y. Ishida, T. Togashi, K. Yamamoto +6
Ultrafast dynamics of graphite is investigated by time-resolved photoemission spectroscopy. We observe spectral features of direct photoexcitations, non-thermal electron distributi…
