About this position
This PhD project at the University of Birmingham focuses on the quantum behaviour of molecules in plasmonic nanocavities, a cutting-edge area at the intersection of physics, chemistry, and materials science. When light interacts with nano-sized metallic structures, it induces collective oscillations of free electrons, known as plasmons. By engineering the geometry and arrangement of these nanostructures, researchers can concentrate light into extremely small volumes, forming nanoplasmonic cavities capable of enclosing single molecules. Plasmons can perturb molecular atoms, inducing unique vibrational modes in chemical bonds, typically resonant in the mid-infrared regime.
Recent advances have demonstrated the possibility of converting these vibrational resonances into the visible spectrum via frequency up-conversion, facilitating easier experimental detection. However, the underlying mechanisms and control strategies for this process remain poorly understood. The successful candidate will develop theoretical tools based on cavity quantum electrodynamics (QED) to model the complex interactions between plasmons and molecular vibrations in confined spaces.
The project also involves designing new cavity types to enhance up-conversion efficiency. The research will be conducted within the Nanophotonics group led by Prof Angela Demetriadou, part of the Metamaterials and Nanophotonics group in the School of Physics and Astronomy.
Collaboration with the Nanophotonics group at the University of Cambridge is also anticipated. The School is recognized for its commitment to diversity and equality, holding both the Institute of Physics Juno Champion and Athena SWAN Silver Award. Funding is available on a competitive basis, covering tuition and a living stipend for 3.5 years.
Applicants should hold or be about to complete an undergraduate degree in Physics (preferably with first class honours or equivalent), and possess strong interests in quantum mechanics, quantum optics, electromagnetism, and mathematical skills. Applications from under-represented groups are strongly encouraged. For further details or informal enquiries, candidates may contact Prof Angela Demetriadou at [email protected].
