Authors: Navarro-Baron, Erik P.; Vinck-Posada, Herbert; Gonzalez-Tudela, Alejandro Journal: NANOPHOTONICS Publication date: 2024/02/25 DOI: 10.1515/nanoph-2023-0843 Abstract: Spontaneous emission is one of the most fundamental out-of-equilibrium processes in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations. In this process, a photon is emitted that can interact with other nearby emitters [...]

Photon-Mediated Interactions near a Dirac Photonic Crystal Slab

Authors: Petrovish Navarro-Baron, Erik; Vinck-Posada, Herbert; Gonzalez-Tudela, Alejandro Journal: ACS PHOTONICS Publication date: 2021/11/17 DOI: 10.1021/acsphotonics.1c00991 Abstract: Dirac energy dispersions are responsible for the extraordinary transport properties of graphene. This motivated the quest for engineering such energy dispersions also in photonics, where they have been predicted to lead to many exciting phenomena. One paradigmatic example [...]

Anisotropic Quantum Emitter Interactions in Two-Dimensional Photonic-Crystal Baths

2020-01-16T12:54:29+01:00Tags: , , , |

Authors: Gonzalez-Tudela, Alejandro; Galve, Fernando Contribution: Article Journal: ACS PHOTONICS Publication date: 2019/01/01 DOI: 10.1021/acsphotonics.8b01455 Abstract: Quantum emitters interacting with two-dimensional photonic-crystal baths experience strong and anisotropic collective dissipation when they are spectrally tuned to 2D Van-Hove singularities. In this work, we show how to turn this dissipation into coherent dipole-dipole interactions with tunable range by [...]
