Complete asymptotic expansions for the relativistic Fermi-Dirac integral

作者:

Highlights:

• Fermi-Dirac integrals appear in problems in nuclear astrophysics, solid state physics or in the fundamental theory of semiconductor modeling, among others areas of application.

• In this paper, we give new and complete asymptotic expansions for the relativistic Fermi-Dirac integral.

• These expansions could be useful to obtain a correct qualitative understanding of Fermi systems.

• The performance of the expansions is illustrated with numerical examples.
