Friedel Oscillations in Relativistic Nuclear Matter

Friedel oscillations in relativistic nuclear matter.

We calculate the low-momentum N-N effective potential obtained in the OBE approximation, inside a nuclear plasma at finite temperature, as described by the relativistic σ-ω model. We analyze the screening effects on the attractive part of the potential in the intermediate range as density or temperature increase. In the long range the potential shows Friedel-like oscillations instead of the usu...

Relativistic nuclear matter in generalized thermo-statistics

The generalized Fermi-Dirac thermo-statistics is developed for relativistic nuclear matter. We introduce the generalized thermodynamic potential using the q-deformed exponential and logarithm. The baryon density has a form of the qexpectation value. Then, we use the mapping of the non-extensive thermo-statistics onto the extensive one. Therefore, the Clausius extensive entropy and the physical ...

Relativistic 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...
