Query: Transverse Kerker Scattering for Angstrom Localization of Nanoparticles   Angstrom precision localization of a single nanoantenna is a crucial step
towards advanced nanometrology, medicine and biophysics. Here, we show that
single nanoantenna displacements down to few Angstroms can be resolved with
sub-Angstrom precision using an all-optical method. We utilize the tranverse
Kerker scattering scheme where a carefully structured light beam excites a
combination of multipolar modes inside a dielectric nanoantenna, which then
upon interference, scatters directionally into the far-field. We spectrally
tune our scheme such that it is most sensitive to the change in directional
scattering per nanoantenna displacement. Finally, we experimentally show that
antenna displacement down to 3 Angstrom is resolvable with a localization
precision of 0.6 Angstrom.
