Doctoral position “Topological Plasmonic Devices"
Activities and responsibilities
We recently demonstrated real-space observation of topological edge states in plasmonic one-dimensional Su-Schrieffer-Heeger (SSH) chains of nanoslit resonators using photoemission electron microscopy (PEEM) (Schurr et al., arXiv:2504.02603, Science Advances (2025), https://doi.org/10.1126/sciadv.aea3844). This achievement places us among the leading groups in experimental topological plasmonics, with unique access to 1 nm-precise nanofabrication and near-field mapping of plasmonic lattices at nanometer resolution.
Building on this foundation, the central idea of this project is to engineer radiative loss and coupling in plasmonic SSH chains to explore non-Hermitian and passive parity-time (PT)-symmetric physics. Control over losses will be introduced by alternating radiant (dipolar) and subradiant (quadrupolar) resonators in an SSH configuration. Crucially, this can be achieved without compromising our established precise control of hopping amplitudes. The resulting structures will exhibit lifetime-split topological modes, non-Hermitian degeneracies, and exceptional points (EPs).

Qualification profile
We welcome applicants with backgrounds from physics, applied physics, nanoscience or related fields with relevant experience in experimental work, ideally including published research. Candidates must hold a master’s degree in a qualifying program (equivalent to a German M.Sc. degree).
The present project is a collaboration of our group with theory (Prof. Thomale) and physical chemistry (Prof. Brixner) for the use of photo-electron emission microscopy (PEEM) as analytical method. Strong communication skills and proficiency in scientific English are therefore required.

We offer
Selected candidates qualify for joining the PhD program at the University of Würzburg or the Graduate School of Science and Technology and will be offered an employment contract (Research Assistant position with social security benefits under German labor law).
