Reflection and refraction properties of laser-driven 2D quantum well: Analogy with Photonic Time Crystal
Igor V. Smetanin, Alexander V. Uskov
It has been demonstrated that a quantum well with optically excited, homogeneous oscillations of a two-dimensional (2D) electron plasma behaves as a photonic time crystal when it s…

Increased output of superradiant light-emitting diodes due to population fluctuations
Igor E. Protsenko, Alexander V. Uskov
The quantum nonlinear Maxwell-Bloch equations for a single-mode laser with a two-level active medium are solved in the LED regime without adiabatic elimination of the medium polari…

Spontaneous emission, collective phenomena and the efficiency of plasmon-stimulated photo-excitation
Igor E. Protsenko, Alexander V. Uskov, Nikolay V. Nikonorov
We find that the spontaneous and collective emissions have a strong influence on the excitation of two-level absorbers (atoms, molecules) interacting in resonance with the plasmoni…
