Distribution of Electric Field and Charge in Superconducting Strips Induced by Hall Effects

摘要

Macroscopic distribution of electric field and electric charge arising from Hall effects in superconducting strip lines is investigated. Vortex motion with Hall effects brings about both a longitudinal electric field E_y (along the strips) and a transverse electric field E_x (across the strips). We analytically determine the electric-field distribution using a scaling law E_x x E_y~m with an exponent 1<=m<2, and then derive a distribution of sheet charge q(x) using a nonlocal relationship between E_x(x) and Q(x). The macroscopic charge arises from polarization of moving vortices.
