Probing quantum geometry with two-dimensional nonlinear optical spectroscopy
Paul Froese, Mark R. Hirsbrunner, Yong Baek Kim
Recent studies have shown that the nonlinear optical response of crystalline systems is fundamentally a quantum geometric property. In this work, we propose two-dimensional coheren…

Topological excitons in moiré MoTe/WSe heterobilayers
Paul Froese, Titus Neupert, Glenn Wagner
Due to the presence of flat Chern bands, moiré transition metal dichalcogenide (TMD) bilayers are a platform to realize strongly correlated topological phases of fermions such as…
