Title: Quantum Twisting Microscopy of Moiré Flat Bands: A Theoretical Perspective

Abstract: Moiré materials with tunable flat bands provide an exceptional platform for realizing strongly correlated and topological phases. Achieving a detailed understanding of their electronic structure, however, remains a major challenge. The recently developed quantum twisting microscope introduces a new tunneling probe for van der Waals materials. In this talk, I will present a theoretical framework for both elastic and inelastic tunneling spectroscopy of moiré flat bands using the quantum twisting microscope. I will discuss how this technique can enable momentum-resolved measurements of electronic spectral functions, neutral collective excitations and superconducting gap structures in magic-angle twisted bilayer graphene.
