Supersolids and Quantum Droplets in Light-Mediated Quantum Gases

About the Project

Are you excited by quantum many-body physics and state-of-the-art experiments with ultracold atoms? This PhD project offers the opportunity to explore emergent phases of matter in ultracold quantum gases, with a particular focus on light-mediated interactions induced by optical feedback and the formation of supersolids - a remarkable phase that combines crystalline order with superfluid flow.

Project Overview

Ultracold atomic gases provide an exceptionally clean and tuneable platform for studying strongly correlated quantum systems. By coupling atoms to structured light fields - ranging from optical lattices to dynamical optical potentials created by optical feedback - this project will investigate how light-mediated interactions can drive self-organisation, pattern formation, and supersolidity. The work will combine experimental measurements with modern theoretical and computational approaches to reveal new regimes of non-equilibrium and collective quantum behaviour. The project is embedded in a broader research environment with opportunities to engage in related studies of lattice physics, nonlinear quantum fluids, and non-equilibrium many-body physics.

Training and Development

As a PhD student, you will gain world-class training in:

• Experimental AMO physics: laser systems, vacuum apparatus, atom cooling and trapping, optical lattices
• Quantum many-body physics: Bose-Einstein condensates, supersolids, self-organisation, non-equilibrium dynamics, phase transitions, optical lattices
• Computational techniques: Python/Matlab based analysis, modelling and simulation of quantum systems, image processing, hardware programming

You will work closely with a research team in a highly collaborative environment, with opportunities to present at national and international conferences and engage with the wider ultracold-atoms community.

Key Details

• Host Institution: University of Strathclyde
• PhD Duration: 3.5 years
• Start Date: 1st October 2026
• Annual Stipend: At UKRI minimum stipend level (projected to be £21,383 for 2026/27)

Candidate Profile

We seek motivated candidates with a strong background in quantum physics or a closely related discipline. Experience in one or more of the following is beneficial:

• Atomic physics, quantum physics, condensed-matter concepts
• Laboratory experience with lasers, optics, electronics, or control systems
• Python/Matlab for data analysis and modelling

International students are also eligible to apply, but they'll need to find other funding sources to cover the difference between the home and international tuition fee. Exceptional international candidates may be provided funding for this difference. Please contact the supervisor for details.
