Interactions and Topology in Quantum Matter: Auxiliary Field Approach & Generalized SSH Models
Patrick J. Wong
Presented in this thesis are a set of projects which lie at the intersection between strong correlations and topological phases of matter. The first of these projects is a treatmen…

The Mott transition as a topological phase transition
Sudeshna Sen, Patrick J. Wong, Andrew K. Mitchell
We show that the Mott metal-insulator transition in the standard one-band Hubbard model can be understood as a topological phase transition. Our approach is inspired by the observa…
