Effective screening of medium-assisted van der Waals interactions between embedded particles
Fiedler, Johannes; Walter, Michael; Buhmann, Stefan Yoshi (Journal article; Peer reviewed, 2021)The effect of an implicit medium on dispersive interactions of particle pairs is discussed, and simple expressions for the correction relative to vacuum are derived. We show that a single point Gauss quadrature leads to ... -
Purcell-induced suppression of superradiance for molecular overlayers on noble atom surfaces
Fiedler, Johannes; Berland, Kristian; Buhmann, Stefan Yoshi (Journal article; Peer reviewed, 2022)We study the impact of an environment on the electromagnetic responses of a molecule in the presence of a dielectric medium. By applying the dipole–dipole coupling between the molecule’s and the environment’s degrees of ...
