Research Interests
My research interest lies in the study of quantum phases and phase transitions. I studied exotic phases, such as topological ordered states and fracton phase, have non-trivial entanglement structure resulting in interesting behaviours, such as ground state degeneracy and anyonic statistics of excitations. I am also interested in continuous phase transitions which can be described by conformal field theories. I use various approaches, including duality mappings and renormalization group, to study them. I also study quantum RG which is a way to realize holographic mapping.
