The University of Bath is inviting applications for the following fully funded PhD project in the Department of Physics.
We are looking for a candidate to start as soon as possible or as discussed with the lead supervisor. Please contact Dr Peter Mosley for more information.
Overview of the Research:
In this PhD project, you will investigate how light-matter interactions in optical cavities can be deployed to develop narrowband single-photon sources, low-loss switches, and scalable quantum gates for photonic quantum technologies.
High-finesse cavities provide significant enhancements of electromagnetic fields, providing a platform to boost interactions between light and matter. In this project, you will explore two different architectures: a centimetre-scale ring cavity formed from mirrors and loaded with a rubidium-filled cell; and silica glass microbubbles that support whispering-gallery modes around their equator and can be filled with liquids or gases. You will learn how to fabricate your own silica microbubbles with a technique recently developed in Bath and use high-stability, narrowband laser systems to couple into the modes supported by both cavities. The goal is to demonstrate how the phase shift imparted on a signal field by two-photon absorption at low light levels can be used for optical switching, and to investigate how cavity-enhanced interactions might modify the statistics of photon sources.
This 3.5-year studentship is funded by the United States Air Force Office of Scientific Research within a well-resourced project led by the primary supervisor, Dr Peter Mosley. Working within the Centre for Photonics and Photonic Materials (CPPM), you will be integrated into a cohort of graduate students in the CPPM with support from post-doctoral researchers working on related projects. You will have the opportunity to present your results in a variety of situations from Centre meetings to major international conferences.
We are seeking applicants who are keen to develop their laboratory skills through working with state-of-the-art tunable laser systems and optical-fibre-integrated technologies in a well-equipped lab. You will enhance your theory and coding skills by modelling the cavities that you build and the interactions that take place within them. You will be expected to take part in weekly Centre meetings including giving research and journal club presentations as well as participating in “Quantum Club”, the CPPM’s journal discussion group focused on quantum optics.
Project keywords: single photons, quantum computing, quantum technologies, photonics, quantum optics.
Candidate Requirements:
Applicants should hold, or expect to receive, a First Class or good Upper Second Class Honours degree (or the equivalent) in Physics or a related subject. A master’s level qualification would also be advantageous.
Non-UK applicants must meet our English language entry requirement.
Enquiries and Applications:
Informal enquiries are welcomed and should be directed to Dr Peter Mosley on email address [Email Address Removed].
NOTE: Applications may close earlier than the advertised deadline if a suitable candidate is found; therefore, we recommend that you contact Dr Peter Mosley and Dr Josh Nunn prior to applying and submit your formal application as early as possible.
Formal applications should be made via the University of Bath’s online application form for a PhD in Physics.
More information about applying for a PhD at Bath may be found on our website.
Funding Eligibility:
To be eligible for funding, you must qualify as a Home student. The eligibility criteria for Home fee status are detailed and too complex to be summarised here in full; however, as a general guide, the following applicants will normally qualify subject to meeting residency requirements: UK and Irish nationals (living in the UK or EEA/Switzerland), those with Indefinite Leave to Remain and EU nationals with pre-settled or settled status in the UK under the EU Settlement Scheme. This is not intended to be an exhaustive list. Additional information may be found on our fee status guidance webpage, on the GOV.UK website and on the UKCISA website.
