Instanton liquid at finite quark density
Abstract
The interaction of light quarks and instanton liquid in the phase of nonzero values of chiral condensate is studied at finite quark/baryon density. Calculating the generating functional in the tadpole approximation we investigate the behaviour of dynamical quark mass and chiral condensate together with instanton liquid density (which shows insignificant increase) as a function of quark/baryon chemical potential. We argue on the noticeable increase of quark density at the point of developing the nonzero magnitude of diquark condensate due only to the quark interaction with the instanton liquid.
