The influence of quantum geometry on the phase boundary and collective excitations of electron liquids and crystals
Paul Froese, Mark R. Hirsbrunner, Yong Baek Kim
Recent experiments on multilayer graphene systems have reinvigorated the study of electron crystallization, now with the inclusion of quantum geometry. In this work, we apply time-…

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 f…
