On the Thomas–Fermi model at the Planck scale

Publication date: Available online 15 January 2019Source: Physics Letters AAuthor(s): Homa Shababi, Kamel OurabahAbstractMany quantum gravity theories predict a minimal length of the order of the Planck length. In this letter, the Thomas–Fermi model is reformulated by taking into account such a prescription. A generalized Thomas–Fermi equation is derived, that reduces to the usual one in the absence of a minimal length. As an application, the model is used to study the dielectric screening process. Estimations of the Fermi length are given for star interior.
