Abstract
A microscopic theory is developed for the Andreev-Bashkin effect in a superfluid two-component weakly nonideal Bose gas. An expression is obtained for the matrix of superfluid densities in the general case of two gases with different densities, particle masses, and scattering lengths. A method for the observation of a drag between superfluid components is proposed.
