  We study the holographic dual of a finite density system with both bosonic
and fermionic degrees of freedom. There is no evidence for a universal
bose-dominated ground state. Instead, depending on the relative conformal
weights the preferred groundstate is either pure AdS-Reissner-Nordstrom, a
holographic superconductor, an electron star, or a novel mixed state that is
best characterized as a hairy electron star.
