Emergent Phases of Electrons in Unbounded Chern Bands

Strongly interacting electrons in topological bands can organize into correlated states with remarkable emergent properties, as exemplified by the fractional quantum Hall effect. Recent developments in rhombohedral graphene have introduced a new paradigm for correlated topological physics: unbounded Chern bands. Unlike conventional Chern bands with discrete translation symmetry, these unbounded bands possess high Berry curvature but have continuous translation symmetry (and hence unbounded momentum). In this talk, I will explore the exotic topological states that can arise in this setting.

Bio:
Trithep Devakul is an assistant professor in the Department of Physics at Stanford University. A theoretical condensed matter physicist, his general research interests lie in exploring the exotic states of matter that can arise in quantum systems. He is currently most interested in studying topological states that can arise in a class of 2D quantum materials known as moiré materials.

Prof. Devakul earned his bachelor’s degree in physics at Northeastern University and his Ph.D. in physics at Princeton University. He completed a postdoc at MIT before joining the Stanford faculty.
