PhD Studentship: Quantum Nanophotonics with Molecules

This PhD project explores the intersection of quantum plasmonics and molecular photonics, aiming to measure quantum light emission from molecules confined within plasmonic optical cavities. Plasmonic cavities, with their ability to confine light at subwavelength scales, enable strong coupling between electromagnetic fields and molecular excitations [1-6]. This coupling can lead to the generation of quantum light, such as single photons or entangled states, critical for quantum communication and sensing applications.

The project involves the development of plasmonic optical cavity configurations, optimized for coupling with molecular vibrational and electronic transitions. By embedding selected organic or hybrid molecules into these cavities, the research will probe the emergence of quantum light through processes like single-photon emission or photon antibunching. A key focus will be temperature-dependent studies, spanning cryogenic to ambient conditions, to understand the role of thermal fluctuations in modulating the molecule-cavity interaction and quantum light generation. Techniques such as photoluminescence spectroscopy and time-resolved photon counting will be employed.

The outcomes are expected to provide insights into the fundamental dynamics of molecule-plasmon coupling and contribute to the development of molecular quantum light sources, paving the way for advancements in nanoscale quantum optics and plasmonic quantum technologies. This research is part of a UKRI Future Leaders Fellowship investigating “the hidden mysteries of light at the atomic scale”. The student will have opportunities to collaborate with leading international research groups at the University of Cambridge, MIT, and UCLA, and to engage with an interdisciplinary team of physicists, chemists, and materials scientists.

Applicants should have completed (or closer to completion) their undergraduate degree in Physics, Material Science, Physical Chemistry or related Physical Sciences (preferably with first-class honours or equivalent). Strong analytical and experimental skills are desirable. The project's specifics will be determined in collaboration with the successful candidate, tailoring the research to their interests.

The project will be conducted within the research group led by Dr. Rohit Chikkaraddy (https://sites.google.com/view/chikkaraddy), based at the Metamaterials and Nanophotonics Research Centre (https://www.birmingham.ac.uk/research/centres-institutes/research-in-physics-and-astronomy/quantum-matter-and-photonics/metamaterials-and-nanophotonics) in the School of Physics and Astronomy at the University of Birmingham, UK.

The School of Physics and Astronomy is an Institute of Physics Juno Champion since 2014 and holder of the Athena SWAN Silver Award. Both initiatives recognise the School’s commitment to promote diversity and equality, and to encourage better practice for all members of the community, whilst also working towards developing an equitable working culture in which all students and staff can achieve their full potential. We welcome applications from all qualified applicants, and encourage applications from traditionally under-represented groups in physics and astronomy including, but not limited to, women and Black, Asian and Minority Ethnic.

Funding is available to UK/EU nationals, covering tuition fees and providing a living stipend for 3.5 years. Non-UK candidates with the appropriate qualifications will be considered.
