• We study a 3/4-filled two-dimensional extended Hubbard model under the fluctuation--exchange approximation. We find that this model undergoes phase separation in a region of nonzero temperature, where the quantum critical phenomenon of charge ordering dominates. By considering the long-range Coulomb interaction that frustrates this phase separation, we present a mechanism for generating a glassy state in a quasi-two-dimensional organic conductor on the verge of charge ordering.
