Magnetically Tuned Continuous Transition from Weak to Strong Coupling in Terahertz Magnon Polaritons
Andrey Baydin, Kenji Hayashida, Takuma Makihara +11
Depending on the relative rates of coupling and dissipation, a light-matter coupled system is either in the weak- or strong-coupling regime. Here, we present a unique system where…
Chiral Phonons with Giant Magnetic Moments in a Topological Crystalline Insulator
Felix G. G. Hernandez, Andrey Baydin, Swati Chaudhary +10
We have studied the magnetic response of transverse optical phonons in PbSnTe films. Polarization-dependent terahertz magnetospectroscopy measurements revealed Zeeman…
Magnetic Control of Soft Chiral Phonons in PbTe
Andrey Baydin, Felix G. G. Hernandez, Martin Rodriguez-Vega +10
PbTe crystals have a soft transverse optical phonon mode in the terahertz frequency range, which is known to efficiently decay into heat-carrying acoustic phonons, resulting in ano…
Spatially resolved spectral phase interferometry with isolated attosecond pulse
Hiroki Mashiko, Ming-Chang Chen, Koji Asaga +5
We characterized spatially resolved spectral phase interferometry with an isolated attosecond pulse (IAP). The measured spatial-spectral interferogram and spectral interference fri…
Observation of Photoinduced Terahertz Gain in GaAs Quantum Wells: Evidence for Radiative Two-Exciton-to-Biexciton Scattering
X. Li, K. Yoshioka, Q. Zhang +9
We have observed photoinduced negative optical conductivity, or gain, in the terahertz frequency range in a GaAs multiple-quantum-well structure in a strong perpendicular magnetic…
Terahertz Faraday and Kerr rotation spectroscopy of BiSb films in high magnetic fields up to 30 Tesla
Xinwei Li, Katsumasa Yoshioka, Ming Xie +16
We report results of terahertz Faraday and Kerr rotation spectroscopy measurements on thin films of , an alloy system that exhibits a semimetal-to-top…
Single-Shot Terahertz Time-Domain Spectroscopy in Pulsed High Magnetic Fields
G. Timothy Noe, Ikufumi Katayama, Fumiya Katsutani +10
We have developed a single-shot terahertz time-domain spectrometer to perform optical-pump/terahertz-probe experiments in pulsed, high magnetic fields up to 30 T. The single-shot d…
