Theory for Quantum correlations in extreme nanoplasmonic structures

When light illuminates nano-sized metallic structures, the free electrons in the metal collectively oscillate, creating `plasmons’. By specifically designing the geometry and arrangement of the nano-metallic structures, one can direct and concentrate light at small enough volumes to enclose even single molecules or quantum emitters. Quantum emitters placed within these small volumes, absorb the plasmons to excite electrons at higher-energy states. Hence, the light (plasmon) and quantum emitters (matter) continuously exchange energy. Using plasmons, one can control how quickly the energy exchange occurs, and tailor the properties of the combined system at room temperature. Hence, using plasmons we can gain access to the fundamental elements of matter. When multiple quantum emitters are placed in a plasmonic nanocavity, quantum correlations emerge at ambient conditions. Such systems form the basis for many future applications in quantum technologies and quantum information processing [1,2,3].

This PhD project focuses on modelling the quantum correlations between multiple emitters in plasmonic nanocavities, performing full-wave numerical calculations to complement the analytical description and eventually to investigate more complex systems. The candidate will also work very closely with the experimental Nanophotonics group, at University of Cambridge.

The PhD candidate should have completed (or about to complete) his/her undergraduate degree in Physics (preferably with first class honours or equivalent). The PhD candidate is expected to have a keen interest on Electromagnetism and/or Quantum Optics.

The project will take place in the Nanophotonics group of Dr Angela Demetriadou (https://www.birmingham.ac.uk/staff/profiles/physics/demetriadou-angela.aspx), which is part of the Metamaterials Research Centre (https://www.birmingham.ac.uk/research/activity/physics/quantum/metamaterials/index.aspx) in the School of Physics and Astronomy, University of Birmingham.

In line with the Department’s Athena SWAN programme, female applicants are particularly welcome to apply.
