Abstract

We interpret the large currents in the c direction (perpendicular to the chains) reported in Hg₃_₈jAsF₆ below 4K as being due to superconducting fluctuations near its mean-field T_c. We show that the unique structure of this material and the strong anisotropy of the electron-phonon interaction lead to fluctuating currents in the c direction, with a critical behaviour characteristic of a one-dimensional system, We show that the unique form of the BCS Hamiltonian gives rise to superconductivity in this quasi-one-dimensional metal, without an interfering Peierls transition.
