Summary
Designer materials are a key research subject in condensed matter physics offering great opportunities to explore emerging new physics and provide pathways to many-body quantum phenomena that are exceedingly difficult to find intrinsically in isolated materials. The key challenge is to retain the individual quantum ground states in the different components in hybrid materials, while simultaneously tuning the strength of the interactions between them. This requires careful nanofabrication and the complexity of such systems makes further progress difficult. Unlike conventional materials, van der Waals heterostructures of 2D materials can be constructed like playing with Lego: they can be simply stacked up at an atomic-scale. These van der Waals heterostructures have generated considerable recent interest as designer quantum materials which allow realization of exotic and often incredible properties. The general goal of this proposal is the experimental realization of 2D topological superconductors in vdW heterostructures, and to study the resulting emergent phases of matter. Subsequently, I will use external stimuli (magnetic field, temperature, and chemistry, external gate) to manipulate them. Finally, I will couple moiré physics with topological superconductivity and show how the moiré is an external factor that allows additional control over the topologically superconducting phase. If the aims of this proposal can be experimentally realized, it could profoundly change future research and technology of topological quantum matter.
