Theory and Numerics of Bosonic Topological Insulator and Self-Dual Quantum Critical Point
A/Prof. Cen-Ke Xu
Department of Physics, UC Santa Barbara, USA

We discuss recent progresses of understanding 2+1d quantum phase transitions, and topological phases. Based on observations from various perspectives, we realize that many 2+1d quantum critical points, though look different through their Lagrangians, may be secretly dual (equivalent) to each other. These dualities give us powerful predictions about universal behaviors of very different systems at the quantum critical points, which can be checked by numerical simulations. We also discuss how to realize part of the physics in experimental systems.
