We are ranked in the top 5 physics and astronomy departments in the Russell Group for our research output. Our world-leading status has been confirmed in the Research Excellence Framework (REF) 2021.
You will be supported by a supervisor who'll help you shape your research topic. You'll also join one of our research groups. Being a member of a research group means that interested people are always on hand to hear your ideas, discuss your results and offer help and encouragement.
You'll be able to attend postgraduate lecture courses, classes and research seminars to broaden your knowledge. There will also be opportunities to attend short courses or summer schools, such as Institute of Physics workshops and NATO Advanced Study Institutes. These bring together experts to give lectures and lead discussions.
We'll encourage you to travel for conferences and research collaborations at other large laboratories and world-class observatories, such as CERN and The European Southern Observatory in Chile.
As a newly qualified PhD in Physics, you'll have many career options open to you. Our students head into non-scientific careers, or take up science-based appointments in the UK. Others go one to postdoctoral research, often in the United States, Europe or, increasingly, Japan.
We invite PhD applications to study within the following research areas:
The University of Southampton is pleased to announce that PGR students from EU and Horizon associated countries joining us in 2026-27 will pay the same as UK PGRs for their PhD.
You can either apply for a structured studentship or propose your own PhD idea.
Structured studentships are advertised PhD projects with a title, supervisor, remit and funding already in place. These projects have been set up through collaborations with industry, external partners or they may have been provided through one of several Centres for Doctoral Training which we take part in.
Taking one of our structured studentships will give you access to additional training, conferences and secondments.
Supermassive black holes in quasars control the growth of their host galaxies by driving powerful outflows from the disks that surround them. Despite their importance, we know almost nothing about these disk winds. In this project, You will construct a physical picture of quasar outflows by modelling their observational signatures.
This project aims to find experimental ways to couple nuclear spin dynamics to the centre of mass motion/oscillation of optically trapped particles. This will allow to use the quantum features of the spins to control and prepare quantum states of motion, such as macroscopic Schrödinger cat states.
This project aims to recalibrate early universe measurements and deliver precise and accurate supermassive black hole (SMBH) masses using the new GRAVITY+ measurements.
This PhD project develops next-generation multicore fibre amplifiers for sustainable submarine networks. The research combines simulation and experiment to create energy-efficient, high-capacity amplification technologies that reduce power consumption, cost per bit, and enhance future global communication infrastructure.
This project aims to explore the turbulent atmosphere of Jupiter using cutting-edge 3D climate simulations. It combines high-performance computing, advanced modelling, and international collaboration to uncover the mechanisms behind giant storms, multiple jets, and exotic weather.
Explore advanced material platforms for UV-VIS photonic integrated circuits. This project will develop low-loss waveguides using wide band-gap materials, enabling breakthroughs in biomedical sensing, environmental monitoring, and compact light engines for high-resolution displays.
Current nonlinear fiber optic devices mainly focus on the visible and near-infrared bands. The project focuses on the development of mid-infrared (MIR) nonlinear optics and integrated nonlinear devices using soft-glass optical fibers to achieve efficient light generation and manipulation in the 2–20 µm spectral region.
A research project within the Doctoral Centre for Advanced Electrical Power Engineering will consider a complex set of plasma phenomena and physical processes taking place during contact opening in DC switches as well as an optimisation of the devices design to extend its applicability for higher currents and voltages.
Dive into the mysterious world of polarization in antiresonant hollow core fibres, where conventional wisdom is turned on its head, and unexpected phenomena emerge every day. Through your insights and innovation, you will shape the future of this cutting-edge technology from data centres, to high-power lasers, to space systems.
A miles-long glass sheath thinner than human hair enshrouds a delicate arrangement of glass tubes having hundred-nm thickness – this is Antiresonant Hollow-Core Optical Fibre – a technology creating new fields in data, quantum, and sensing. This PhD will explore means of deploying these novel fibres in compact coils for sensing.
This project aims to interrogate one of the most pressing problems of modern physics, can we describe gravity with quantum mechanics? A thought experiment wherein a test mass in superposition may or may not produce a superimposed gravitational field was proposed and this studentship will contribute to its realisation.
This project develops a gyroscope using a levitated nanodiamond with nitrogen-vacancy (NV) centers. These systems enable coupling between the mechanical angular momentum of a levitated nanoparticle and its internal electronic spins, opening pathways for quantum control and precision sensing.
This project will involve the development of novel resource-efficient quantum algorithms for molecular simulation and their adaption in state-of-the-art quantum hardware in the cloud and with collaborators.
Recent discoveries of exotic forms of light, structured in space and in time, promise novel ways of transferring information, delivering energy, and even manipulating matter. The project will focus on the generation, light-matter interactions, and applications of spatiotemporally structured electromagnetic waves.
This project investigates thermonuclear (Type I) X-ray bursts on neutron stars through numerical simulations of flame spreading and ignition. You'll model burst dynamics, compare results with observations, and explore broader applications of the code to stellar flame propagation and exoplanetary atmospheres, developing strong computational and programming expertise.
Binaries containing white dwarfs, neutron stars or black holes produce many key astrophysical systems, from supernovae to merging black holes. However, their long-term evolution remains poorly understood. In this project, you will develop a next-generation framework for determining the evolution compact binaries using the latest theoretical, observational and computational developments.
We offer a wide range of fully funded studentships. We run several of our PhD studentships in partnership with doctoral training centres, meaning you'll benefit from enhanced training and in some cases funding as well.
These studentships:
Doctoral training centres offer fully funded studentships which include:
