Janet Hung

Research Interests

I am interested in the application of AdS/CFT in the study of condensed matter systems, such as low dimensional quantum liquids and superconductors.
I have also been interested in understanding the holographic prescription for computing entanglement entropy.
More recently I have also taken an interest in the study of topological states of matter.
