Abstract
Within the kinetic energy driven superconducting mechanism, the doping and magnetic field dependence of the superfluid density in cuprate superconductors is studied. The electromagnetic response kernel is evaluated by considering both couplings of the electron charge and electron magnetic momentum with an external magnetic field and employed to calculate the superfluid density based on the specular reflection model for a purely transverse vector potential, then the main features of the doping and magnetic field dependence of the superfluid density in cuprate superconductors are well reproduced.
