There is a long history of probing fundamental quantum mechanics using atomic physics. In our group, we investigate complex many-body phenomena such as quantum phase transitions and manipulation of low-dimensional quantum systems both in and out of equilibrium using ultracold atomic gases on atom chips.
The project will utilise the current rubidium Bose-Einstein condensate (BEC) apparatus to test a fundamental question of the nature of quantum phase [1, 2]. The answer to that question requires very precise control of quantum atomic ensembles. While the coherent splitting of a BEC into two sub-ensembles was achieved more than a decade ago , this project will entail the creation and manipulation of at least three coherent sub-ensembles using the radio-frequency dressed potentials in a way that is not a straightforward extension of previous work.
The successful candidate is expected to work on an atom chip based ultracold atom system. The effort will entail the experimental design, as well as theory and numerical simulations.
The PhD student will play a central role in this investigation and will learn a wide array of tools in atomic physics, quantum physics and numerical modelling. Emphasis on various aspects of research (modelling, experimental work, sample fabrication) will be adjusted to the interests and skills of the student.
The PhD student on this project will obtain experience in the followings:
Neutral cold atom systems, Bose-Einstein condensates
Experimental techniques such as optics, laser spectroscopy and electronics
Atom chips and printed circuit board technology
Quantum theory optionally
Publish and present research in high-quality international journals and conferences
Report orally and prepare papers reporting progress and delivery of project outcomes
Proactively contribute to the activities of the research group
In addition to a good Honours or Masters degree, the candidate should have a background in Atomic and Quantum Physics and have excellent IT skills including programming.
Our group uses neutral atoms as precision sensors and combines a mix of fundamental and applied research. We aim to bring quantum technology out of the laboratory so that it can be harnessed by non-specialists. At the same time, we want to discover more about how the quantum world works. In particular, we use ultra-cold atomic gases to study complex many-body phenomena.
