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…

Imaging and Identification of Single Nanoplastic Particles and Agglomerates

Ambika Shorny, Fritz Steiner, Helmut Hörner +1

Currently the extent of nanoplastic in the environment can only be estimated by extrapolation from the plastic waste that can be detected. To be able to quantify the whole extent o…

Properties of quantum emitters in different hBN sample types particularly suited for nanophotonic integration

Ambika Shorny, Hardy Schauffert, James C. Stewart +11

Single photon emitters in two-dimensional (2D) hexagonal boron nitride (hBN) are promising solid-state quantum emitters for photonic applications and quantum networks. Despite thei…

Massively degenerate coherent perfect absorber for arbitrary wavefronts

Yevgeny Slobodkin, Gil Weinberg, Helmut Hörner +3

One of the key insights in the emerging field of non-Hermitian photonics is that well-established concepts like the laser can be operated in reverse to realize a 'coherent perfect…
