Perspectives on Physics of ExB Discharges Relevant to Plasma Propulsion and Similar Technologies
Igor D. Kaganovich, Andrei Smolyakov, Yevgeny Raitses +22
This paper provides perspectives on recent progress in the understanding of the physics of devices where the external magnetic field is applied perpendicularly to the discharge cur…
Hermitian-Einstein metrics from noncommutative instantons
Kentaro Hara, Akifumi Sako, Hyun Seok Yang
We show that Hermitian-Einstein metrics can be locally constructed by a map from (anti-)self-dual two-forms on Euclidean to symmetric two-tensors introduced in "Gra…
Amplification due to Two-Stream Instability of Self-Electric and Magnetic Fields of an Ion Beam Propagating in Background Plasma
Erinc K. Tokluoglu, Igor D. Kaganovich, Johan A. Carlsson +2
Propagation of charged particle beams in background plasma as a method of space charge neutralization has been shown to achieve a high degree of charge and current neutralization a…
Generation of forerunner electron beam during interaction of ion beam pulse with plasma
Kentaro Hara, Igor D. Kaganovich, Edward A. Startsev
The long-time evolution of the two-stream instability of a cold ion beam pulse propagating though the background plasma is investigated using a large-scale one-dimensional electros…
Kinetic simulations of ladder climbing by electron plasma waves
Kentaro Hara, Ido Barth, Erez Kaminski +2
The energy of plasma waves can be moved up and down the spectrum using chirped modulations of plasma parameters, which can be driven by external fields. Depending on whether the wa…
Noncommutative Deformations of Locally Symmetric Kähler manifolds
Kentaro Hara, Akifumi Sako
We derive algebraic recurrence relations to obtain a deformation quantization with separation of variables for a locally symmetric Kähler manifold. This quantization method is one…
