Statistical fluxes and the Curie-Weiss metal state

Abstract

We predict a new state of matter in the triangular t-J model in a high doping regime. Due to the altered role of quantum statistics the spins are `localized' in statistical Landau orbits, while the charge carriers form a Bose metal that feels the spins through random gauge fields. In contrast to the Fermi-liquid state, this state naturally exhibits a Curie-Weiss susceptibility, large thermopower, and linear-temperature resistivity, explaining the physics of \textrm{Na}${}_x$\textrm{CoO}${}_2$ at $x>\mathrm{0.5.}$ A `smoking gun' prediction for neutron scattering is presented.
