In the first experiment, I will discuss transport experiments on twisted bilayers of the monolayer semiconductor WSe2 (Wang et al, Nature Materials 19, 861 (2020) and […]

Title: Towards realizing twistronics on demand Speaker: Cory R. Dean, Department of Physics, Columbia University Abstract: The ability to isolate atomically thin crystals, such as graphene, boron nitride, and the transition metal dichalcogenides, and then mechanically layer them to form new heterostructures has driven a recent revolution in materials design. These layered structures are held […]

Title: Searching for New Matter Speaker: Sinéad Griffin, Lawrence Berkeley National Laboratory   Abstract: The past decade has seen a huge surge of interest in matter that cannot be described by our standard theories such as Landau-Ginzburg theory or the Standard Model. For example, the theoretical proposal and subsequent experimental realization of topological phases in […]
