Zeeman polaritons as a platform for probing Dicke physics in condensed matter
T. Elijah Kritzell, Jacques Doumani, Tobias Asano +11
The interaction of an ensemble of two-level atoms and a quantized electromagnetic field, described by the Dicke Hamiltonian, is an extensively studied problem in quantum optics. Ho…
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…
Ultrastrong Magnon-Magnon Coupling Dominated by Antiresonant Interactions
Takuma Makihara, Kenji Hayashida, G. Timothy Noe +13
Exotic quantum vacuum phenomena are predicted in cavity quantum electrodynamics (QED) systems with ultrastrong light-matter interactions. Their ground states are predicted to be va…
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…
Dielectric cross-shaped resonator based metasurface for vortex beam generation in Mid-IR and THz wavelengths
Raghu Dharmavarapu, Ken-ichi Izumi, Ikufumi Katayama +7
Metasurfaces are engineered thin surfaces comprising two dimensional (2D) arrays of sub-wavelength spaced and sub-wavelength sized resonators. Metasurfaces can locally manipulate t…
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…
