This fully funded PhD project at The Dodd-Walls Centre (Massey University, Auckland, New Zealand) offers an exciting opportunity to explore the elusive phenomenon of odd-frequency superfluidity using advanced theoretical and computational physics methods. Odd-frequency superfluidity, where fermions pair in time rather than space, remains a largely theoretical concept with only indirect experimental evidence to date. This project aims to address fundamental questions about the existence and stability of odd-frequency superfluids, potentially revealing new pathways to superfluidity or novel properties in conventional systems. As a PhD student, you will develop and analyze quantum many-body models that exhibit odd-frequency fermionic pairing correlations, with a particular focus on models relevant to ultracold atom experiments. The primary research tool will be quantum Monte Carlo simulations, and you will contribute to the development of the open-source code base Rimu.jl. Additional theoretical and approximate methods may also be employed, depending on the research direction. The project is part of a larger, Marsden Fund-supported collaboration involving a postdoctoral fellow and an international team of experts in condensed-matter theory, Monte Carlo simulations, and ultracold-atom experiments from New Zealand, Germany, and the USA. This collaborative environment provides excellent opportunities for networking, skill development, and exposure to cutting-edge research in quantum physics. Funding: The position is fully funded through the Marsden Fund of New Zealand, covering tuition fees and providing a stipend for living expenses. Eligibility: Applicants should have a strong background in theoretical and computational physics, quantum mechanics, and solid state physics. Experience with quantum Monte Carlo simulations, programming, or open-source code development (e.g., in Julia or similar languages) is highly desirable. A relevant undergraduate or master's degree in physics or a closely related field is required. Good communication skills and the ability to work collaboratively in an international research team are expected. Application deadline: 30 May 2026. How to apply: Submit your application via the FindAPhD project link. For enquiries, contact Prof. Joachim Brand at [email protected] . Prepare your CV, academic transcripts, and a cover letter outlining your research interests and relevant experience. References: For further reading, see: [1] K.
