Constructing a chiral dipolar mode in an achiral nanostructure
Jörg S. Eismann, Martin Neugebauer, Peter Banzer
We discuss the excitation of a chiral dipolar mode in an achiral silicon nanoparticle. In particular, we make use of the electric and magnetic polarizabilities of the silicon nanop…
Ultrafast relaxation dynamics of the antiferrodistortive phase in Ca doped SrTiO3
M. Porer, M. Fechner, E. Bothschafter +19
The ultrafast dynamics of the octahedral rotation in Ca:SrTiO3 is studied by time resolved x-ray diffraction after photo excitation over the band gap. By monitoring the diffraction…
Mirror-Symmetric Heterogeneous Resonant Nanostructures: Extrinsic Chirality and Spin-Polarized Scattering
Sergey Nechayev, Paweł Woźniak, Martin Neugebauer +2
We investigate a geometrically symmetric gold-silicon sphere heterodimer and reveal its extrinsic chiroptical response caused by the interaction with a substrate. The chiroptical r…
Weak measurement of elliptical dipole moments by C point splitting
Sergey Nechayev, Martin Neugebauer, Martin Vorndran +2
We investigate points of circular polarization in the far field of elliptically polarized dipoles and establish a relation between the angular position and helicity of these C poin…
Transverse Kerker Scattering for Angstrom Localization of Nanoparticles
Ankan Bag, Martin Neugebauer, Paweł Woźniak +2
Angstrom precision localization of a single nanoantenna is a crucial step towards advanced nanometrology, medicine and biophysics. Here, we show that single nanoantenna displacemen…
