Theory of phonon spectroscopy with the quantum twisting microscope
The quantum twisting microscope, or QTM, is a powerful new scanning probe based on momentum-conserving tunneling across a twistable finite-area interface between van der Waals layers placed on a tip with a flat top and on a substrate. The authors develop here a theory of QTM measurements probing phonon dispersions and electron-phonon couplings of van der Waals materials. The results inform the quest to understand superconductivity in twisted bilayer graphene and provide a case study for QTM investigations of collective modes.
