Detecting the Berry curvature in photonic graphene
R. L. Heinisch, H. Fehske
We describe a method for measuring the Berry curvature from the wave-packet dynamics in perturbed arrays of evanescently coupled optical waveguides with honeycomb lattice structure…
Surface mode hybridization in the optical response of core-shell particles
E. Thiessen, R. L. Heinisch, F. X. Bronold +1
We present an exact rewriting of the Mie coefficients describing the scattering of light by a spherical core-shell particle which enables their interpretation in terms of an hybrid…
Scattering of infrared light by dielectric core-shell particles
E. Thiessen, F. X. Bronold, R. L. Heinisch +1
We study the scattering of infrared light by small dielectric core-shell particles taking a sapphire sphere with a CaO core as an example. The extinction efficiency of such a parti…
Scattering of two-dimensional Dirac fermions on gate-defined oscillating quantum dots
C. Schulz, R. L. Heinisch, H. Fehske
Within an effective Dirac-Weyl theory we solve the scattering problem for massless chiral fermions impinging on a cylindrical time-dependent potential barrier. The set-up we consid…
