Abstract

Recent experiments on bilayer semiconductors have revealed long-lived interlayer excitons and provided indications of exciton condensation through tuning gate voltages. These developments open new possibilities for engineering strongly correlated electronic phases in controllable settings.
In this talk, I will explore how interlayer exciton condensation in the presence of doped charge carriers can be used to engineer a variety of correlation-driven phenomena. I will first show how such systems can emulate spin-density-wave quantum criticality observed in correlated electron materials, and discuss the resulting prospects for unconventional superconductivity. I will then turn to multilayer heterostructures, where exciton condensation can result in a marginal Fermi liquid phase without the need for fine-tuning to a quantum critical point.
