PhD Studentship in Theoretical Cosmology and Quantum Fields

Swansea University is offering a fully funded PhD studentship focusing on theoretical aspects of quantum field theory in cosmological spacetimes. The research will investigate the physics of the early Universe, examining expanding backgrounds, particle production, and quantum information concepts such as entanglement and decoherence. The successful candidate will employ analytical techniques from general relativity, statistical physics, and non-equilibrium quantum dynamics to link theoretical models with observable signatures. The project offers an opportunity to contribute to modern cosmological research with connections to gravitational-wave observatories and cosmic microwave background measurements.

• Investigate theoretical aspects of quantum field theory in cosmological spacetimes and expanding backgrounds.
• Examine quantum information concepts including entanglement, quantum coherence, and information flow in the early Universe.
• Utilize frameworks from open quantum systems, decoherence, and non-equilibrium quantum dynamics.
• Connect theoretical developments with potential observable signatures in cosmological and astrophysical data.
• Collaborate on linking research with next-generation probes such as gravitational-wave observatories and cosmic microwave background measurements.
