Heavy-ion collision experiments at RHIC and LHC along with lattice calculations brought a new understanding of the quark-gluon matter nature at high temperature and zero, or small chemical potential. Quark matter physics in a regime of nonzero density and low temperature remains challenging. Such conditions are expected to exist in compact neutron stars. The talk will be focused on the pre-critical region above the color superconducting phase. Contrary to the BCS superconductivity, the fluctuation regime covers a wide temperature interval and displays interesting phenomena. Strong quantum electrical conductivity and unusual sound absorption will be discussed. The involved physics is at the intersection of QCD and condensed matter theory.
