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 ...
