Dr Gary Liu

Research Associate

Background

I am I-Kang Liu, also known as Gary Liu. In October 2019, I joined Newcastle University as a research associate to work on the dynamics of ultra-cold Bose gases with Prof. Nick Proukakis.


Before this, in 2016 I obtained my Ph. D degree in Physics at National Changhua University of Education, Taiwan with Prof. Shih-Chuan Gou, who leads the Ultra-Cold Atom Theory (UCAT) group, and then continued as a postdoctoral researcher alongside my three-year alternative national service, finished in 2019. 


My research interests are Bose-Einstein condensates, topological defects and non-equilibrium dynamics. I am also interested in topological properties of quantum systems. I have been implementing a classical-field theory to study the dynamics of BEC at finite temperatures with collaboration with experimentalists. I also theoretically investigate novel systems/structures in a variety of ultracold Bose gas systems.

Research

My research interests are Bose-Einstein condensate, topological defects inside that and topology of quantum systems. I have been implementing a classical-field theory to study the dynamics of BEC at finite temperatures with collaboration with experimentalists. I also theoretically investigate novel systems/structures in a variety of ultracold Bose gas systems.


Recently we are studying how ultracold Bose gas re-equilibrates across a phase transition via quenches and corresponding scaling behaviours around the critical point.


I am also interested in multi-component condensate with extra-degree of freedom and system-dependent symmetries, yielding different type of defects, such as skyrmion, half-quantized vortices in spinor condensate systems.
