Introduction to the theory and application of a unified Bohm criterion for arbitrary-ion-temperature collision-free plasmas with finite Debye lengths

Abstract: At present, identifying and characterizing the common plasma–sheath edge (PSE) in the conventional fluid approach leads to intrinsic oversimplifications, while the kinetic one results in unusable over-generalizations. In addition, none of these approaches can be justified in realistic plasmas, i.e., those which are characterized by non-negligible Debye lengths and a well-defined non-negligible ion temperature. In an attempt to resolve this problem, we propose a new formulation of the Bohm criterion [D. Bohm, T… Show more

“…In terms of future applications, it is planned to combine SR via GP also with neural networks of complex topology, to profit from the great exploratory power and flexibility of deep learning 50,51 . Upgrades of the methodology to address times series with memory, recursive functions [52][53][54][55] and distributed quantities are also quite advanced.…”
