Abstract
Ginzburg-Landau-Gor'kov equations and the expression for the current for coexisting superconductivity-charge-density-wave (CDW) systems near the superconducting transition temperature have been derived from microscopic theory. Two particular features are discussed: an additional current due to the sliding CDW, and the CDW-induced anisotropy, which lead to interesting physical consequences including the Meissner effect with a contribution from both currents. Measurements of CDW-induced anisotropy can be used to probe the microscopic mechanism of coexistence.
