Showing papers on "Schwinger variational principle published in 2019"
TL;DR: In this article, the authors investigated the scattering of charged particles in quantum plasmas (QPs) by employing a fully quantum mechanical treatment within the framework of the Schwinger variational principle in the momentum space, and the role of quantum mechanical effects in plasma is examined by comparing the results in QP with the corresponding results in classical weakly coupled plasma for which effective potential has been described by Debye-Huckel potential.
Abstract: The scattering of charged particles in quantum plasmas (QPs) has been investigated by employing a fully quantum mechanical treatment within the framework of the Schwinger variational principle in the momentum space. The effective potential in QP has been described by a modified Debye-Huckel potential. Scattering phase shifts for various plasma screening strengths have been obtained accurately by a convergent scheme of the Schwinger variational method. The accuracy of the results has been corroborated by solving the corresponding Schrodinger equation with accurate numerical techniques. The nature of scattering for a wide range of plasma screening has been studied. The role of quantum mechanical effects in plasma is examined by comparing the results in QP with the corresponding results in classical weakly coupled plasma for which effective potential has been described by Debye-Huckel potential. Special emphasis has been made to study the dynamics at low energies. In particular, a detailed investigation has been made on the zero-energy resonance phenomenon.The scattering of charged particles in quantum plasmas (QPs) has been investigated by employing a fully quantum mechanical treatment within the framework of the Schwinger variational principle in the momentum space.
