摘要：
We investigate the renormalization of the elastic matrix (elastic softening) of a vortex array aligned along the c-axis due to the presence of a spatially homogeneous force-free c-axis current. The applied current decreases the stability of the vortex solid phase with respect to thermal fluctuations, shifting the vortex-lattice melting to lower temperatures and/or fields.
