Description
It is generally believed that systems with two fermion species that form
Cooper pairs form a neutral state, where the number densities of the two
fermion species are equal. This belief is based on mean field calculations
with a zero-range contact interaction. We investigate whether this claim still
holds if a Yukawa model is employed, where the interaction range is finite.
Our results indicate that the conclusions drawn from the zero-range
interaction case may not be as general as initially believed. Our findings
also support the results of an earlier Dyson-Schwinger based study that found
the color-flavor locked phase to be non-neutral.
