Dirac equation predicts negative and positive energy solutions. To solve the problem of the free electron ground state, Dirac suggested that negative energy states are occupied. The Dirac equation dispersion relations are reminiscent of condensed matter band structures, and the occupied condensed matter states are referred to as the Fermi sea.
