CM Seminar: Nitin Kaushal – Quantum Matter Institute Title: Realization of magnetically frustrated Wigner crystals and a novel multiorbital model in transition metal dichalcogenide based moiré materials Abstract: Moiré materials constructed using the transition metal dichalcogenide (TMD) bilayers have been used to simulate the Hubbard model with long range Coulomb interactions procuring the lattice Wigner […]

CM Seminar: Andrea Young – University of California Santa Barbara Title: Magnetism and superconductivity in rhombohedral graphene multilayers: triplet superconductivity, intervalley coherence, and spin orbit coupling  Abstract: The electronic band structure of rhombohedral graphene multilayers hosts van Hove singularities at which the single particle of states diverges.  I will discuss experiments in which we use […]

CM Seminar: Jeff Sonier – Simon Fraser University Title: Muon Studies of Superconducting UTe2 Abstract: Recently discovered UTe2 is believed to be a long-sought spin-triplet superconductor, but its magnetic properties and superconducting order parameter are matters of controversy. The observation of a nonzero polar Kerr effect in the superconducting state of UTe2 single crystals exhibiting […]
