About Me
I am a Gordon and Betty Moore Postdoctoral Fellow at Condensed Matter Theory Center, Department of Physics, University of California, Berkeley. I currently work with professors Dung-Hai Lee and Joel Moore in the research field of condensed matter theory. Before joining Berkeley, I received my Ph.D. in Physics at University of Colorado Boulder. Prior to the pursuit of Ph.D., I obtained my M.S. in Physics and B.S. in Physics with Minor in Mathematics at National Taiwan University. See the CV page for more details about me!
Research Interest
As a condensed matter theorist, I am interested in the nature of condensed matter systems involving interaction, singular density of states, symmetry, topology/geometry, and/or nonequilibrium (disorder and/or Floquet). I enjoy studying these systems with a balanced combination of theoretical modeling, analytic calculation, and numerical computation. I have worked on and been continuously interested in various research topics, including but not limited to:
Functional-renormalization-group and Hartree-Fock(-Bogoliubov) studies of interacting-electron phases
Correlated phases in kagome flat band
Van Hove correlated phases on hexagonal lattices: Moiré systems and kagome metals AV3Sb5 with A = K, Rb, and Cs
Band geometry: Properties related to quantum metric
Band topology: Symmetry protection, edge and corner states, etc
Magnetoresistance in semimetals
Tensor network methods
Disordered quantum spin systems
See the Research page if you are interested in more details, and the Publications page for a complete list of my work!
