Special Condensed Matter Seminar Speaker: Allen Scheie Title: "The old and the new: Probing elemental gadolinium and quantum entanglement with neutron scattering" Abstract: Doing experiments on quantum materials often not nearly as hard as interpreting those experiments. In this talk I discuss two projects where neutron scattering data was analyzed in a new way to […]
Title: New Pathways for Topological Flat Bands, and Roton Condensate in Fractional Quantum Anomalous Hall Systems  Abstract: Recent studies on topological flat bands in moiré superlattices have revealed fascinating new phenomena, such as the fractional quantum anomalous Hall effect (FQAH). In this talk, we will discuss  two interrelated topics: (1) new strategies for creating exact […]
Title: Moiré magnetism in twisted two-dimensional magnets Abstract: Moiré superlattice emerges from the interference between two mismatched atomic lattices, and it has led to tremendous success in designing and tailoring the electronic states in two-dimensional (2D) homo- and hetero-structures. Yet, the power of moiré superlattice in controlling the spin degree of freedom and thus modifying the magnetic states is much less […]
