Project description
Controlling and manipulating interlayer excitons in heterobilayers
Monolayer transition metal dichalcogenides (TMDs) have tightly bound excitons and enhanced Coulomb interactions that are easy to access and control optically. When two monolayers of different materials are combined into heterobilayers of TMDs, long-lived dipolar interlayer excitons emerge. The study of TMD heterobilayers has significantly advanced our understanding of many-body physics. However, the ability to control individual interlayer excitons and interactions among them has not been achieved. With the support of the Marie Skłodowska-Curie Actions programme, the IXIXions project aims to do so. It will use nanoscale-patterned graphene electrical gates to trap and manipulate interlayer excitons, starting with single ones and progressing to small populations that could pave the way to quantum simulation.
Objective
Monolayer transition metal dichalcogenides (TMDs) exhibit exceptional properties to study many-body physics with direct optical control through their tightly-bound excitons and enhanced Coulomb interactions. Even more versatile physics emerge in heterobilayers of TMDs, which host long-lived dipolar interlayer excitons (IXs), with promising potential for quantum simulation experiments and realizing a plethora of correlated phases. In recent years, TMD heterobilayers have been at the center of many-body physics where effects such as the formation of a Wigner crystal, the demonstration of Hubbard model quantum simulation and the realization of Bose-Einstein condensates are just a few examples. However, deterministic control of single IXs and therefore interactions among individual IXs has not been shown. For MSCA project, I propose to study many-body physics of IXs, starting from the individual IX level and then progressing to small and well controlled IX populations. To do so I will use nanoscale patterned graphene electrical gates to trap and manipulate them. This top-down approach is scalable and flexible, allowing for the creation of arbitrary trap potentials and geometries. The scope of this two-year project is to use this technique to fundamentally study the exciton-exciton interactions that are at the basis of the exciting physics that arises from these new materials. However, the scientific potential of a method that can site-control IXs does not end here, this technique could form the foundation for quantum-simulation, demonstration of Hubbard model physics and exploring new quantum phases.
