We invite applications for a PhD project developing a next-generation solid-state nuclear clock based on the recently observed ^229mTh isomer transition (~148 nm). This program targets breakthroughs in precision timekeeping and enables new tests of fundamental physics at the intersection of nuclear, solid-state physics, and frequency metrology.

The PhD will focus on 3 tightly coupled themes:

Thorium isotopes in host materials

Identify and optimise crystal hosts to maximise lifetime/visibility and minimise environmental sensitivity. Work includes ultra-sensitive defect/impurity characterisation and isotope/elemental analysis.

Optical access to the isomer transition

Design and implement a vacuum-ultraviolet excitation and detection platform to interrogate the 148 nm transition, leveraging frequency-comb-based upconversion/high-harmonic generation concepts. 

Towards fundamental physics tests and applications Develop measurement concepts that leverage the nuclear transition for tests of fundamental constants and symmetries, evaluate pathways to dark-matter/new-force searches and quantum-technology applications.

The candidate will work in a highly interdisciplinary environment with access to cryogenic measurement infrastructure, precision spectroscopy instrumentation, and strong collaboration opportunities with leading international groups (UCLA and European partners), including potential travel. The project will be based in the Quantum and Dark Matter Metrology Group at UWA.

Suitably qualified applicants must meet the admissions requirements outlined in UWA’s Handbook.

Preferred background in Physics or closely related disciplines, particularly one or more of: spectroscopy, photonics/lasers, frequency metrology, cryogenics, RF/microwave resonators, solid-state materials, or nuclear/atomic physics. Experience in experimental instrumentation and data analysis (e.g., Python) is advantageous.

Interested applicants should email a recent CV and academic transcripts to Maxim Goryachev (maxim.goryachev@uwa.edu.au) with the subject line: “PhD Application – Solid-State Nuclear”.
