The screening and wake potentials around a test charge in an electron–ion quantum plasma are studied, by using the linear dielectric response formalism. The short range screening potential in quantum plasmas is found to be significantly different from the Debye–Hückel shielding potential, while the wake potential has a long-range oscillatory behavior. Both short and long range potentials may lead to the trapping of other charges of the same polarity.
