By considering the nonperturbative effects associated with the fundamental modular region, a new phase of a Gluon Plasma at finite density is proposed. It corresponds to the transition from glueballs to nonperturbative gluons which condense at a nonvanishing momentum. In this respect the proposed phase is analogous to the color superconducting LOFF phase for fermionic systems.
