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: 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 […]

Host: Yi Li Critical Filaments and Fractal-Mediated Superconductivity in Quasiperiodic Twisted Bilayer Graphene The electronic properties of quantum materials depend on the symmetry, topology, and spatial structure of electron wave functions. It was previously shown that superconductivity can be boosted by spatially rarified wave functions shaped by random or structured inhomogeneity. Recently, the twisting of […]
