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 ...

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 (

Phase Control of Spontaneous Emission [PDF]
Physical Review Letters, 1998 We use the phase difference of two lasers with equal frequencies for the control of spontaneous emission in a four-level system. Effects such as extreme spectral narrowing and selective and total cancellation of fluorescence decay are shown as the relative phase is varied.

Physical Review Research, 2023 Entanglement is known to decay even in isolated systems, an effect attributed to spontaneous emission. This fragility of entanglement can be exacerbated by entanglement sudden death (ESD), where entanglement drops to zero abruptly within a finite time ...
