job description
Join the National University of Singapore (NUS) as a Research Fellow in our groundbreaking Multi-Ion Lutetium (Lu+) Optical Clocks project, redefining precision timekeeping for quantum technologies, GPS-free navigation, and fundamental physics tests. This role offers a unique opportunity to work at the forefront of quantum metrology while collaborating with a world-class team in a hybrid-remote setup from Bali, Indonesia.
As part of this initiative, you will contribute to developing next-generation atomic clocks with unprecedented accuracy, leveraging trapped-ion systems and advanced laser cooling techniques. Your work will have direct applications in satellite-based timing, dark matter detection, and tests of Einstein’s relativity. The position combines theoretical modeling, experimental design, and hands-on laboratory work in a dynamic, interdisciplinary environment.
NUS is a globally ranked institution (QS Top 10), offering cutting-edge facilities, international collaborations, and a vibrant research ecosystem. This role is ideal for a PhD holder in Physics, Quantum Engineering, or related fields with a passion for precision measurement and quantum systems.
Responsibility
- Design, build, and optimize multi-ion Lu+ optical clock systems, including ion trapping, laser cooling, and state detection.
- Develop and implement high-stability laser systems (e.g., ultra-narrow linewidth lasers) for clock transitions.
- Conduct frequency stability and accuracy evaluations using advanced metrological techniques (e.g., Ramsey spectroscopy, quantum non-demolition measurements).
- Collaborate with cross-functional teams to integrate clock systems with time-transfer technologies (e.g., optical fiber links, satellite-based methods).
- Publish high-impact research in peer-reviewed journals (e.g., Nature, Science, PRL) and present findings at international conferences.
- Mentor junior researchers and PhD students in experimental quantum optics and precision measurements.
- Contribute to grant proposals and secure funding for future projects in quantum metrology.
- Stay abreast of advancements in atomic clocks, quantum sensors, and trapped-ion technologies.
Qualifications
- PhD in Physics, Quantum Optics, Atomic Physics, or a related field (required).
- Proven experience with trapped-ion systems, optical clocks, or laser cooling (e.g., Lu+, Yb+, Sr).
- Hands-on expertise in ultra-stable lasers, frequency combs, and high-finesse cavities.
- Strong background in quantum metrology, spectroscopy, or precision measurements.
- Proficiency in LabVIEW, Python, or MATLAB for data acquisition and analysis.
- Excellent written and verbal communication skills for scientific publications and collaborations.
- Ability to work independently in a hybrid-remote research environment with periodic travel to NUS Singapore.
- Familiarity with vacuum systems, electronics, and control software for experimental setups.
