Explorations in twisted trilayer graphene

The moiré patterns generated by twisting van der Waals materials has given rise to a new regime of physics in which electronic interactions and quantum geometry are at the forefront. While most studies have focused on two-layer materials, going to three layers or more layers vastly increases the space of possibilities, which is just beginning to be explored. I will discuss recent theoretical and experimental explorations into the phase space of twisted trilayer graphene. I will focus on helical trilayer graphene (HTG), where recent experiments have revealed a rich set of correlated physics, and also discuss other promising magic angle trilayer graphene systems for future studies.
