Skyrmion topology of scalar waves in real and momentum space
Nai H. Kwong, Ewan M. Wright, Jan Wingenbach +4
Generalizations of magnetic skyrmions to the context of other areas of physics, such as plasmonics, optics (including microcavity polaritons) and even water waves have become an im…
Quantum sampling in hybrid light-matter systems with mixed statistics
Franziska Barkhausen, Laura Ares, Stefan Schumacher +1
Boson sampling is one of the most prominent methods to verify quantum advantage, harnessing the computational complexity of the permanent of a network matrix. Similar quantum sampl…
Polarization- and wave-vector selective optical metasurface with near-field coupling
Helene Wetter, Jan Wingenbach, Falk Rehberg +3
Metasurfaces are a powerful tool for manipulating light using small structures on the nanoscale. In most meta-surfaces, near-field couplings are treated as unfavorable perturbation…
Exceptional rings in nonlinear non-Hermitian planar optical microcavities: implementation, signal enhancement, and topology
Jan Wingenbach, Laura Ares, Xuekai Ma +4
Non-Hermitian systems hosting exceptional points (EPs) exhibit signal enhancement and unconventional mode dynamics. Going beyond isolated EPs, here we report on the existence of ex…
Universal Topology of Exceptional Points in Nonlinear Non-Hermitian Systems
N. H. Kwong, Jan Wingenbach, Laura Ares +4
Exceptional points (EPs) are non-Hermitian degeneracies where eigenvalues and eigenvectors coalesce, giving rise to unusual physical effects across scientific disciplines. The conc…
Entanglement between dependent degrees of freedom: Quasiparticle correlations
Franziska Barkhausen, Laura Ares Santos, Stefan Schumacher +1
Common notions of entanglement are based on well-separated subsystems. However, obtaining such independent degrees of freedom is not always possible because of physical constraints…
