Hall effect in a system of coupled Luttinger chains

Andrei Lopatin

(Department of Physics and Astronomy, Rutgers University)

Abstract:  I consider the Hall effect in a system of weakly coupled one-dimensional chains with the Luttinger interaction within each chain.  At zero temperature, using a perturbation theory in the inter-chain hopping term, I find a power law dependence of the Hall conductivity on the magnetic field with an exponent depending on the interaction constant.  The perturbation theory becomes valid if the magnetic field is sufficiently large.  I will discuss some aspects of a generalization of the theory to finite temperatures.
