PHYSICAL REVIEW E 86, 036406 (2012)Negative energy waves and quantum relativistic Buneman instabilities The quantum relativistic Buneman instability is investigated theoretically using a collective Klein-Gordon model for the electrons and a cold fluid model for the ions. The growth rate and unstable wave spectrum is investigated in different parameter regimes corresponding to various degrees of relativistic and quantum effects. The results may be important for streaming instabilities involving ion dynamics in very dense plasmas.

Surface morphology of a Cu substrate flattened by a 2″ photoemission‐assisted ion beam source

“…UV light of wavelength 172 nm was used to irradiate a sample from a Xe excimer lamp through a fused quartz window. In this study, a 2 00 Cu substrate, whose work function is 4.4 eV, [13] was used. A photograph of the Cu substrate on a sample holder is shown in Fig.…”

Ion-beam–plasma interaction effects on electrostatic solitary wave propagation in ultradense relativistic quantum plasmas

“…Apart from the aforementioned (linear) beam instability, one might expect solitary wave propagation to be affected by nonlinear beam-plasma or kinetic instabilities, such as Buneman type instabilities [55,56] or even Landau damping [57,58], a kinetic effect expectedly overlooked in the fluid picture adopted herein.…”

A Mathematical Modelling with Zakharov System for Langmuir Wave in Unmagnetized Plasma

“…In 1920 Langmuir wave discovered by Irvin Langmuir and Levi Tonks [5]. when plasma wave accelerate electron and its acceleration is in the comparision of phase velocity of the wave and this process performs in the form of damp mode which is known as Landau damping [6] when in any conducting media electron density changes its value fast oscillatory form in the ultraviolet region [7].…”
