CMSA Quantum Matter in Mathematics and Physics: Numerical investigations of models of the cuprates

CMSA EVENTS

Thomas Peter Devereaux - Stanford University

Richard Feynman once said "Anyone who wants to analyze the properties of matter in a real problem might want to start by writing down the fundamental equations and then try to solve them mathematically. Although there are people who try to use such an approach, these people are the failures in this field. . . ”

I will summarize efforts to solve microscopic models of the cuprates using quantum Monte Carlo and density matrix renormalization group computational methods, with emphasis on how far one can get before failing to describe the real materials. I will start with an overview of the quantum chemistry of the cuprates that guides our choices of models, and then I will discuss "phases" of these models, both realized and not. I will lastly discuss the transport properties of the models in the "not-so-normal" regions of the phase diagram.
