Dielectric screening in the nonextensive Thomas-Fermi model

The dielectric screening process is revisited within the theoretical framework of the nonextensive Thomas-Fermi model with thermal effects. The nonextensive counterpart of the Fermion distribution function is used. It is found that the nonextensive corrections (which vanish in the zero-temperature limit) are more noticeable as the nonextensive character of the electrons becomes important. Our results should assist in interpreting the screening in dense stellar medium.
