Second-order nonlinear optical response of graphene
Yongrui Wang, Mikhail Tokman, Alexey Belyanin
Although massless Dirac fermions in graphene constitute a centrosymmetric medium for in-plane excitations, their second-order nonlinear optical response is nonzero if the effects o…
Squeezing of thermal fluctuations in four-wave mixing in a Λ-scheme
Maria Erukhimova, Mikhail Tokman
We theoretically investigate the mechanism of two-mode quadrature squeezing in regime of four-wave mixing in a Λ-scheme of three-level atoms embedded in a thermal reservoir. We dem…
The features of a quantum description of radiation in an optically dense medium
M. D. Tokman, M. A. Erukhimova, V. V. Vdovin
This paper is devoted to the theory of quantum electromagnetic field in an optically dense medium. Self-consistent equations describing interaction between a quantum field and a qu…
Continuous wave lasing between Landau levels in graphene
Yongrui Wang, Mikhail Tokman, Alexey Belyanin
We predict the general feasibility and demonstrate the specific design of the THz laser operating between Landau levels in graphene placed on a polar substrate in a magnetic field…
Superradiant Decay of Cyclotron Resonance of Two-Dimensional Electron Gases
Qi Zhang, Takashi Arikawa, Eiji Kato +9
We report on the observation of collective radiative decay, or superradiance, of cyclotron resonance (CR) in high-mobility two-dimensional electron gases in GaAs quantum wells usin…
