Sharp signature of DDW quantum critical point in the Hall coefficient of the cuprates

Sudip Chakravarty, Chetan Nayak, Sumanta Tewari +1

We study the behavior of the Hall coefficient, $R_H$, in a system exhibiting $d_{x^2-y^2}$ density-wave (DDW) order in a regime in which the carrier concentration, $x$, is tune…
