Vanishing Hall Constant in the Stripe Phase of Cuprates
Abstract
The Hall constant RH is considered for the stripe structures. In order to explain the vanishing of RH in LNSCO at x = 1/8, we use the relation of RH to the Drude weight D as well as direct numerical calculation, to obtain results within the t-J model, where the stripes are imposed via a charge potential and a staggered magnetic field. The origin of RH ~ 0 is related to a maximum in D and the minimal kinetic energy in stripes with a hole filling ~ 1/2. The same argument indicates on a possibility of RH ~ 0 in the whole range of static stripes for x < 1/8.
