Description

A strange metal has a resistivity which is smaller than h/e^2, with a linear dependence on temperature at low temperatures. I will describe recent progress in realizing such metals in theoretical models. Numerical studies of a random t-J model show strange metal behavior - I will argue that this is connected to a time reparameterization Schwarzian mode, similar to that found in the SYK model.This same mode has been connected in earlier work by others to maximal chaos.
