Second harmonic generation in graphene dressed by a strong terahertz field
Mikhail Tokman, Sergei B. Bodrov, Yuri A. Sergeev +5
We observe enhanced second-harmonic generation in monolayer graphene in the presence of an ultra-strong terahertz field pulse with a peak amplitude of 250 kV/cm. This is a strongly…
Optical properties and electromagnetic modes of Weyl semimetals
Qianfan Chen, A. Ryan Kutayiah, Ivan Oladyshkin +2
We present systematic theoretical studies of both bulk and surface electromagnetic eigenmodes, or polaritons, in Weyl semimetals. We derive the tensors of bulk and surface conducti…
Plasma losses from mirror trap, initiated by microwave radiation under electron cyclotron resonance conditions
D. A. Mansfeld, A. V. Vodopyanov, M. D. Tokman +3
Plasma of a stationary ECR discharge sustained by gyrotron radiation at a frequency of 24 GHz and a power of up to 600 W in a mirror magnetic trap was studied. At pressures near th…
Difference frequency generation of surface plasmon-polaritons in Landau quantized graphene
A. Ryan Kutayiah, Mikhail Tokman, Yongrui Wang +1
We develop a rigorous quantum-mechanical theory of the nonlinear optical process of difference frequency generation of surface plasmon-polaritons in Landau-quantized graphene. Alth…
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…
