Abstract

Anderson suggested that the temperature dependence of the normal-state Hall coefficient in the high-T(c) superconductors comes from two distinct relaxation rates: a longitudinal relaxation rate (tau(tr)-1) due to holon-spinon scattering and a transverse relaxation rate (tau(H)-1) due to spinon-spinon scattering. A generalized Drude model that incorporates these magnetic-field-induced anisotropy in charge-relaxation rates yields another possible signature of Anderson's conjecture: cyclotron resonance at omega = omega(c)tau(H)/tau(tr), where omega(c) is the cyclotron frequency. We discuss the feasibility of observing this new signature.
