Professor Xia-Ji Liu

Professor, ARC Future Fellow


Liu earned her PhD degree from Tsinghua University in 2001. She was a postdoc at European Laboratory for Non-Linear Spectroscopy (LENS, 2002-2003) and at the University of Queensland (2004-2006). Over the last fifteen years, Liu has been employed via continuous fellowships: The University of Queensland Postdoctoral Fellowship (2006-2008), ARC Australian Research Fellowship (2009-2014) and ARC Future Fellowship (step 2, 2015-2019). The latter two were hosted by Swinburne University of Technology. She is currently a Professor at Swinburne.

Her research interests are in the overlapping areas of quantum optics, atomic and molecular physics, and condensed matter physics. Driven by fast-growing experimental capabilities in ultra-cold atoms, her research has resulted in the development of several important quantum theories of ultra-cold Fermi gases, Bose gases, and Bose-Fermi mixtures. These areas of research all have immediate experimental applications and great implications for future advanced technologies. Liu has published over 140+ papers in peer-reviewed journals, including 22 publications in prestigious Nature Physics, Physics Reports and Physical Review Letters.  Her career-long ISI citations and h-index are 4100+ and 35, respectively (see

PhD topics and outlines

Quantum Few-Body Systems, Fermi/Bose Polarons and Virial Expansion : Quantum virial expansion is an entirely new direction to handle strong correlations. It allows a controllable expansion to be worked out even in three dimensions, in terms of a small parameter - the fugacity. It provides an elegant way to bridge the few-body and the many-body worlds. Our specific schemes in this topic include the high-order virial coefficients et al.

Ultracold Atoms with Synthetic Spin-Orbit Coupling: Recent realization of synthetic gauge fields in ultracold atoms has led to a new frontier. Here,we are interested in the characterization of novel topological fermionic superfluids and possible exotic Bose-Einstein condensates with non-trivial spin-textures. 


Available to supervise honours students.

Honours topics and outlines

Ultradilute quantum droplets: Over the past few years, a newly discovered phase of ultracold, dilute quantum droplets has attracted increasingly attention in different fields of physics. The purpose of this project is to develop better microscopic theories of quantum droplets and to solve some challenging theoretical difficulties in this field.
