Coherent Perfect Absorption of Arbitrary Wavefronts at an Exceptional Point
Helmut Hörner, Lena Wild, Yevgeny Slobodkin +3
A Coherent Perfect Absorber (CPA) exploits the interferometric nature of light to deposit all of a light field's incident energy into an otherwise weakly absorbing sample. The down…

Van der Waals chain: a simple model for Casimir forces in dielectrics
H. Horner, L. M. Rachbauer, S. Rotter +1
The Casimir force between dielectric bodies is well-understood, but not the Casimir force inside a dielectric, in particular its renormalization. We develop and analyse a simple mo…
