PhD Studentship: Quantum Interferometry for Dark Matter Searches

Axions, hypothesised particles and leading candidates for dark matter, offer an intriguing solution to outstanding mysteries in fundamental physics. This project will explore innovative detection strategies leveraging quantum-enhanced interferometry.

You will work on developing and implementing novel techniques involving optical cavities, squeezed sources of light, and single-photon detectors to search for axion-induced signatures. Squeezed light, a quantum state with reduced noise in one quadrature, can surpass classical sensitivity limits, while high-finesse optical cavities will amplify subtle axion signals. Single-photon detectors, with their ability to detect weak light signals with high fidelity, will play a crucial role in achieving quantum-limited detection precision.

The project is at the intersection of quantum optics, precision measurement, and particle physics. You will: (i) design and simulate quantum optical systems for axion detection, (ii) build and test experimental setups using state-of-the-art photonics and interferometric techniques, (iii) analyse data to identify potential axion signals and refine detection limits.

The successful candidate will join a dynamic research group with expertise in quantum optics, dark matter searches, gravitational-wave detection, and collaborating with international teams. Applicants should have a strong background in physics, engineering, or a related discipline, with interest or experience in quantum technologies and fundamental physics.

The project will be supervised by Prof Denis Martynov (d.martynov@bham.ac.uk).
