Abstract

Ion beam-plasma interaction is an area of fundamental importance in the physics of charged matter. In the ultra-high density and ultra-low temperature limit, quantum effects (manifested via electron degeneracy) become significant and the classical treatment is invalidated. In this paper, we investigate, from first principles, the occurrence of electrostatic excitations in an ultradense (quantum) electron-ion plasma permeated by a tenuous negative-ion beam. The analytical framework relies on a quantum-hydrodynamic model, which incorporates an electron momentum equation that consistently takes into account the equation of state of the Fermi (degenerate) electron gas.
