Quantum analysis of a multi-frequency laser with a photonic time crystal
Igor Protsenko, Alexander Uskov
The present study considers the operation of a laser that incorporates a photonic time crystal (PTC), the purpose of which is to generate a field characterised by multiple widely s…
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…
Effect of Tamm surface states on hot electron generation and Landau damping in nanostructures metal-semiconductor
Alexander V. Uskov, Igor V. Smetanin, Igor E. Protsenko +2
The hot electron generation in plasmonic nanoparticles is the key to efficient plasmonic photocatalysis. In the paper, we study theoretically for the first time the effect of Tamm…
Perturbation approach in Heisenberg equations for lasers
Igor E. Protsenko, Alexander V. Uskov
Nonlinear Heisenberg-Langevin equations are solved analytically by operator Fourier-expansion for the laser in the LED regime. Fluctuations of populations of lasing levels are take…
Landau damping in hybrid plasmonics
Alexander V. Uskov, Jacob B. Khurgin, Igor V. Smetanin +2
Landau Damping (LD) mechanism of the Localized Surface Plasmon (LSP) decay is studied for the hybrid nanoplasmonic (metal core/dielectric shell) structures. It is shown that LD in…
A Single-Emitter Gain Medium for Bright Coherent Radiation from a Plasmonic Nanoresonator
Pu Zhang, Igor Protsenko, Vahid Sandoghdar +1
We theoretically demonstrate the generation and radiation of coherent nanoplasmons powered by a single three-level quantum emitter on a plasmonic nanoresonator. By pumping the thre…
