Description
Moiré systems have emerged as a highly tunable platform to study emergent electronic phenomena, enabling effectively materials-based quantum simulators. A key to microscopic understanding of the correlation physics is to unravel the electronic structure of these materials. Because of the low energy scales and flat bands with band widths on the order of a few millielectronvolts, spectroscopic characterization with ultra-high energy resolution is desirable. Quasiparticle interference imaging can provide such resolution, however is inherently difficult to interpret. I will show how using realistic simulation of quasi-particle interference from real-space tight-binding models provides predictions for the QPI in moiré materials, and will show comparison to experimental results both for graphene and TMDC heterostructures.
