High temperature superconductivity and strange metal behavior near a metallic quantum critical point" By Samuel Lederer (Cornell)

It has long been conjectured that quantum critical points (QCPs) are at the root of some of the most fascinating phenomena in the solid state, including the high temperature superconductivity and “strange metal” behavior of cuprate superconductors. Though much progress has been made in the theory of QCPs, those which occur in metals (and may be relevant to the high temperature superconductors) are still poorly understood despite more than four decades of effort. I will discuss the results of numerically exact Quantum Monte Carlo simulations of a model of a metallic QCP towards an Ising nematic ordered phase. Time permitting, I will also discuss an analytical computation of the Raman response for a similar model in a tractable weak coupling regime.
