Semiclassical Treatment of the Dirac Sea Contribution for Finite Nuclei
نویسندگان
چکیده
Dirac sea corrections for bulk properties of finite nuclei are computed within a self-consistent scheme in the σ-ω model. The valence part is treated in the Hartree approximation whereas the sea contribution is evaluated semiclassically up to fourth order in h̄. Numerically, we find a quick convergence of the semiclassical expansion; the fourth order contributing much less than one percent to the binding energy per nucleon. PACS: 21.60.-n

Elimination of the vacuum instability for finite nuclei in the relativistic s-v model
The s-v model of nuclei is studied at leading order in the 1/N expansion thereby introducing the selfconsistent Hartree approximation, the Dirac sea corrections and the one fermion loop meson self-energies in a unified way. For simplicity, the Dirac sea is further treated within a semiclassical expansion to all orders. The well-known Landau pole vacuum instability appearing in this kind of theo...
متن کامل00 1 Bound states of anti - nucleons in finite nuclei
We study the bound states of anti-nucleons emerging from the lower continuum in finite nuclei within the relativistic Hartree approach including the contributions of the Dirac sea to the source terms of the meson fields. The Dirac equation is reduced to two Schrödinger-equivalent equations for the nucleon and the anti-nucleon respectively. These two equations are solved simultaneously in an ite...

متن کاملSemiclassical time evolution and quantum ergodicity for Dirac-Hamiltonians
Within the framework of Weyl calculus we establish a quantum-classical correspondence for the time evolution of observables generated by a Dirac-Hamiltonian. This includes a semiclassical separation of particles and antiparticles. We then prove quantum ergodicity for Dirac-Hamiltonians under the condition that a skew product of the classical relativistic translational motion and relativistic sp...
متن کاملShell corrections for finite depth potentials: Particle continuum effects
Shell corrections of finite, spherical, one-body potentials are analyzed using a smoothing procedure which properly accounts for the contribution from the particle continuum, i.e., unbound states. Since the plateau condition for the smoothed single-particle energy seldom holds, a new recipe is suggested for the definition of the shell correction. The generalized Strutinsky smoothing procedure i...
