Relativistic calculations of atomic structure
This paper is intended to give a review on relativistic atomic structure calculations [1] with emphasis on the Multiconfigurational-Dirac-Foek method, Dr Crossley has summarized in his preeeeding paper most of the non-relativistic methods whieh lead to good binding energies and transition probabilities. Both quantities are espeeially important in astrophysies and plasma physies. Sinee relativis...
متن کاملRelativistic SPH Calculations of Compact Binary Mergers
We review recent progress in understanding the hydrodynamics of compact binary mergers using relativistic smoothed particle hydrodynamics (SPH) codes. Recent results are discussed for both double neutron stars and black hole – neutron star binaries. The gravitational wave signals from these mergers contain a lot of information about the masses and radii of the stars and the equation of state of...

متن کاملRelativistic ring-diagram nuclear matter calculations.
A relativistic extension of the particle-particle hole-hole ring-diagram many-body formalism is developed by using the Dirac equation for single-particle motion in the medium. Applying this new formalism, calculations are performed for nuclear matter. The results show that the saturation density is improved and the equation of state becomes softer as compared to corresponding Dirac-Brueckner-Ha...
متن کاملRelativistic density functional calculations for Pt2.
First full-relativistic density functional calculations with the extension of the spin-polarization functional for the relativistic density functional theory in their collinear and noncollinear form are presented here for the molecular system Pt2. The agreement with experiment is very good.
