6 Dirac Sea Contribution in Relativistic Random Phase Approximation
نویسندگان
چکیده
In the hadrodynamics (QHD) there are two methods to take account of the contribution of negative-energy states in the relativistic random phase approximation (RRPA). Dawson and Furnstahl made the ansatz that the Dirac sea were empty, while according to the Dirac hole theory the sea should be fully occupied. The two methods seem contradictory. Their close relationship and compatibility are explored and in particular the question of the ground-state (GS) instability resulting from Dawson-Furnstanhl's ansatz is discussed.

Dirac Sea Contribution in Relativistic Random Phase Approximation
In the relativistic random phase approximation there are two methods to take account of the contribution of negative energy states. Dawson and Furnstahl made the ansatz that the Dirac sea were empty, while the Dirac hole theory postulated the sea should be fully occupied. The two methods seem contradictory. Their close relationship and compatibility are studied and enunciated. PACS: 21.60. Jz, ...
متن کاملEffects of the Dirac Sea on the Giant Monopole States
Effects of the Dirac sea on the excitation energy of the giant monopole states are investigated in an analytic way within the σ − ω model. The excitation energy is determined by the relativistic Landau-Migdal parameters, F0 and F1. Their analytic expressions are derived in the relativistic random phase approximation(RRPA) without the Dirac sea, with the Pauli blocking terms and with the full Di...
متن کاملThe time-dependent relativistic mean-field theory and the random phase approximation
The Relativistic Random Phase Approximation (RRPA) is derived from the Time-dependent Relativistic Mean Field (TD RMF) theory in the limit of small amplitude oscillations. In the no-sea approximation of the RMF theory, the RRPA configuration space includes not only the ususal particle-hole ph-states, but also αh-configurations, i.e. pairs formed from occupied states in the Fermi sea and empty n...
متن کاملIsoscalar compression modes in relativistic random phase approximation
A fully consistent relativistic RPA calculation is performed for the monopole and dipole compression modes in nuclei. The emphasis is put on the effects of Dirac sea states which are generally neglected in relativistic RPA calculations. It is found that these effects can be quite important for the isoscalar monopole mode. The main contributions from the pairs of Fermi to Dirac sea states are th...
متن کاملCausality in Relativistic Many Body Theory
Dirac sea effects are perhaps the most interesting characteristic of relativistic many body theory. In nuclear matter e.g. the effective mass of the nucleons and their coupling to the mesons undergo considerable corrections due to vacuum fluctuations [1], [2]. In addition, relativistic many body theory predicts strong corrections of the properties of hadrons at high nuclear matter densities. Un...
