Enhancement of the spontaneous emission in subwavelength quasi-two-dimensional waveguides and resonators
Mikhail Tokman, Zhongqu Long, Sultan AlMutairi +3
We consider a quantum-electrodynamic problem of the spontaneous emission from a two-dimensional (2D) emitter, such as a quantum well or a 2D semiconductor, placed in a quasi-2D wav…
Purcell enhancement of the parametric down-conversion in two-dimensional nonlinear materials
Mikhail Tokman, Zhongqu Long, Sultan AlMutairi +4
Ultracompact nonlinear optical devices utilizing two-dimensional (2D) materials and nanostructures are emerging as important elements of photonic circuits. Integration of the nonli…
Magneto-polaritons in Weyl semimetals in a strong magnetic field
Zhongqu Long, Yongrui Wang, Maria Erukhimova +2
Exotic topological and transport properties of Weyl semimetals generated a lot of excitement in the condensed matter community. Here we show that Weyl semimetals in a strong magnet…
Stability of High-Density Two-Dimensional Excitons against a Mott Transition in High Magnetic Fields Probed by Coherent Terahertz Spectroscopy
Qi Zhang, Yongrui Wang, Weilu Gao +5
We have performed time-resolved terahertz absorption measurements on photoexcited electron-hole pairs in undoped GaAs quantum wells in magnetic fields. We probed both unbound- and…
