PhD Studentship: Engineering Quantum States with Molecules in Plasmonics Nanocavities

When light illuminates nano-sized metallic structures, the free electrons in the metal collectively oscillate, creating `plasmons', which can concentrate light at extremely small volumes. If molecules are placed in this volume, the light (plasmon) and molecule (matter) continuously exchange energy at such rapid rate that they blend together to form hybrid states at room temperature (strong coupling regime). Plasmonic nanocavities (with gaps between metallic structures of ~1-2nm) support multiple plasmon/photonic modes that all can simultaneously interact with multiple molecules, forming very complex quantum states that are not well understood yet. This project uses the plasmon mode excitation to engineer and form quantum states between multiple emitters within plasmonic nanocavities.

This PhD project will focus on developing the necessary theoretical tools, using cavity quantum electrodynamic (QED) descriptions, to model and understand this complex interaction between plasmons in small gaps and multiple molecules/emitters, to design a system where specific quantum states are engineered and controlled by the plasmon excitation.

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 keen interest on Quantum Mechanics, Quantum Optics and Electromagnetism and good mathematical skills.

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 at the University of Birmingham. The candidate will also work very closely with the Nanophotonics group based at University of Cambridge and a theoretical chemistry group based in UCL.

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