Terahertz two-dimensional coherent spectroscopy: unlocking coherent quantum intraband nonlinear dynamics
Se Jin Park, In Hyeok Choi, Jeong Woo Han
Quantum materials host a rich spectrum of low-energy collective excitations- phonons, magnons, plasmons, polaritons, and Higgs modes- that fundamentally govern their emergent prope…
Generalizing Thermal Transport in High-Contrast Metamaterials through Interfacial Fresnel Reflection
Seung Hyeon Ham, Yu Min Kim, In Hyeok Choi +1
The rapid growth of generative AI has intensified the need for efficient heat dissipation in large-scale data centers. To control heat flow, thermal metamaterials with layered stru…
Extreme Terahertz Nonlinearity of AlGaN/GaN-based Grating-Gate Plasmonic Crystals
Pavlo Sai, Vadym V. Korotyeyev, Dmytro B. But +12
We present a novel approach to enhance THz nonlinearity by the resonant excitation of two-dimensional plasmons in grating-gate plasmonic crystals. Using a high-electric-field THz p…
