Opening a new window into opto-twistronics

Structure-property interlinkage has been a long-lasting and intriguing paradigm in quantum materials studies. Recently, the great versatility of creating new quantum phases via manipulating the twist degree of freedom in van der waals materials have been demonstrated. One question is, how would the twist change the philosophy of light-matter interactions? In this talk, I will discuss our low temperature optically coupled microwave impedance microscopy setup and its implications on imaging excitonic excitations in twistronic systems, and how this novel technique can be employed to study the previously inaccessible quantum beauty lurking in electron excitation, transfer, and transport at the nanometer scale.
