Thomas Fermi Screening Length in q-Deformed Statistical Mechanics

Abstract

The q-deformed statistical mechanics for fermions has been used to investigate the Thomas-Fermi screening length at finite temperature. Considering linear response, the calculations have been made at weakly nondegenerate regime. The results show that q-deformation has significance effects on screening length at higher temperatures. It is also shown that the q-deformation effects vanish at zero temperature limit. One can find that more correction terms of deformation have more effects on screening length. The bahaviour of screening length is different for different values of q.
