modify the properties of materials by a small change of their twist angle. To date, however, twisted devices are generally fabricated with a fixed angle that cannot be modified once the device has been made. An in-situ “twistronics” apparatus that can bring
into contact two van-der-Waals (vdW) layers and probe the hybrid interface with varying twist angle could be the ideal tool to explore correlated physics in a variety of such interfaces. We recently developed the Quantum Twisting Microscope (QTM), capable
of performing such in-situ twisting. I will present various experiments performed with this microscope, demonstrating quantum interference at room temperature, probing the conductance of in-situ twisting interfaces and imaging local energy dispersions of twisted
graphene under applied pressure. Additionally, I will describe the generalization of these experiments into cryogenic temperatures. <o:p></o:p></span></p>
