Relation of Dawson Furnstahl's Empty Sea Ansatz to Dirac's Hole Theory

  • There are two methods to take account of the contribution of negative energy states in the relativistic random phase approximation. One is due to Dawson and Furnstahl. They made the ansatz that the dirac sea is empty. The other is the Dirac hole theory, which postulated that the sea should be fully occupied. The two methods seem contradictory concerning the way through which the negative–energy states contribute. The relation between the two theories is studied and the conditions under which the Dawson-Furnstahl theory is a good approximation to the Dirac theory are enunciated.

Abstract: There are two methods to take account of the contribution of negative energy states in the relativistic random phase approximation. One is due to Dawson and Furnstahl. They made the ansatz that the dirac sea is empty. The other is the Dirac hole theory, which postulated that the sea should be fully occupied. The two methods seem contradictory concerning the way through which the negative–energy states contribute. The relation between the two theories is studied and the conditions under which the Dawson-Furnstahl theory is a good approximation to the Dirac theory are enunciated.
