Collective Spontaneous Emission Modulated by Strong Coupling in Hyperbolic Metamaterials
PhotonicsWe study the collective spontaneous emission of two quantum emitters (QEs) placed near a semiconductor hyperbolic metamaterial (HMM) composed of a multilayer quantum well (MQW) and doped n+-In0.53Ga0.47As.

Anisotropic Purcell Effect and Quantum Interference in Fractal Aggregates of Nanoparticles
Photonics, 2023 We study theoretically the emergence of an anisotropic Purcell factor in random two-dimensional fractal aggregates of nanoparticles. These nanoparticles can either be metallic nanoparticles made of silver, which exhibit surface plasmon resonances, or ...

Spontaneous-emission-enabled dynamics at the threshold of a directly modulated semiconductor laser
, 2021 Chaos in semiconductor lasers or other optical systems has been intensively studied in the past two decades. However, modulation around threshold has received much less attention, in particular in gain-modulated semiconductor lasers.

Generalized Weisskopf‐Wigner model of triboelectroluminescence
EcoMat, 2021 The phenomenon of triboelectroluminescence is studied using a generalization of the Weisskopf‐Wigner model of spontaneous emission in an electronic two‐level system. An irreversible and exponential transfer of charge results from the model.

Quantum electrodynamics in anisotropic and tilted Dirac photonic lattices
New Journal of Physics, 2021 One of the most striking predictions of quantum electrodynamics is that vacuum fluctuations of the electromagnetic field can lead to spontaneous emission of atoms as well as photon-mediated interactions among them.

Two-Level Systems with Broken Inversion Symmetry
Proceedings, 2019 This research analyzes the impact of the asymmetry of the quantum system and the range of control possibilities offered by dispersive media and the nanostructures. I investigated the asymmetric behavior of a two level system in the Jaynes-Cummings model (
