Abstract
The dispersion relation and instability of dust acoustic waves (DAWs) in an unmagnetized dusty plasma with two different temperatures for ions, two different temperatures for electrons, and dust charge fluctuations are investigated. Ions and electrons are assumed to be Maxwellian distributed. The orbital limited motion theory (OLM) is used to derive dust charge fluctuations. The conditions for the instability are found to be significantly modified by the effects of two different temperatures of ions (electrons), dust charge fluctuations, density ratio of ions and density ratio of electrons. Furthermore, it is observed that there is only damping rate in such dusty plasma.
期刊介绍：
Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
