Description
I will present our recent results on a model of itinerant SU(2) electrons with random exchange. This model hosts a quantum critical point separating two distinct metallic phases as a function of doping: a Fermi liquid with a large Fermi surface volume and a low-doping phase with local moments ordering into a spin-glass. This quantum critical point has non-Fermi liquid properties characterized by T-linear Planckian behavior, ω/T scaling and slow spin dynamics of the Sachdev-Ye-Kitaev (SYK) type.
