Talk title: From Quantum Magnets to Magnetic Thermoelectrics: Short-Range Spin Correlations and the Secrets They Keep Speaker: Benjamin Frandsen, Brigham Young University Abstract: Short-range magnetic correlations have been increasingly recognized in recent years for their importance in contexts as widely varied as geometrically frustrated magnetism and functional magnetocaloric materials. Neutron scattering provides experimental access to […]

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 […]
