Position Details
Background & Context
The Computational Nano Optics research group focuses on development and application of numerical methods for modeling, simulation, and optimization of nanophotonic devices. Single-photon sources of highest quality and yield are essential for quantum technology applications, in particular, in long-range communication in quantum repeater networks, in quantum metrology, and in quantum computing schemes. Nanostructured environments in the form of nanoresonators boost the otherwise low efficiencies of quantum dipole emitters. Numerical simulation and optimization are essential for the design of these nanoresonators. A full quantum-electrodynamical (QED) description of quantum dipole emitters including their interaction with nanostructures and light is not practical due to complexity. Instead, the classical Maxwell equations are often solved, particularly for the optimization of nanostructures. QED and classical Maxwell calculations can be linked, as both treatments yield identical results for key quantities such as the Purcell factor.
Within the framework of a MATH+ collaborative project of Humboldt University of Berlin and ZIB, the aim is to develop and advance the numerical treatment of microscopic light emitters in resonant photonic environments. The advertised position is part of these activities.
The successful candidate will work closely with the project team and with further collaboration partners. The position offers an opportunity to contribute to the active field of photonic quantum technologies and actively help shape the scientific advancement of the field, in particular with respect to modeling, simulation, and optimization.
