Some Issues of the BCS-BEC Crossover for Dense Quark Matter

We explore the possible BCS-BEC crossover on strong-interacting matter and its implications for the system's equation of state. The study will be focus on different phases of dense quark-matter beyond nuclear density and at vanishing temperatures. We show that in the strongly coupled 2SC phase of color superconductivity no BCS-BEC crossover can take place due to the system's color neutrality.
