Recorded 11 April 2022. Garnet Chan of California Institute of Technology, Chemistry, presents "Lattice models and ab initio descriptions of correlated materials" at IPAM's Model Reduction in Quantum Mechanics Workshop. Abstract: I will describe some work in our group and with collaborators on characterizing the properties of correlated electron materials, such as the cuprates, using low energy models and using all-electron ab initio calculations.
