Spacecharge waves in magnetized and collisional quantum plasma columns confined in carbon nanotubes
Abstract
We study the dispersion relation of electrostatic waves propagating in a column of quantum magnetized collisional plasma embraced completely by a metallic singlewalled carbon nanotubes. The analysis is based on the quantum linearized hydrodynamic formalism of collective excitations within the quasistatic approximation. It is shown when the electronic de Broglie's wavelength of the plasma is comparable in the order of magnitude to the radius of the nanotube, the quantum effects are quite meaningful and our model anticipates one acoustical and two optical spacecharge waves which are positioned into three propagating bands. With increasing the nanotube radius, the features of the acoustical branch remain unchanged, yet two distinct optical branches are degenerated and the classical behavior is recovered. This study might provide a platform to create new finite transverse cross section quantum magnetized plasmas and to devise nanometer dusty plasmas based on the metallic carbon nanotubes in the absence of either a drift or a thermal electronic velocity and their existence could be experimentally examined.

The nonlinear coupling between collisional drift waves and a lowerhybrid pump wave is studied in a magnetized dusty plasma cylinder. A dispersion relation for the collisional drift wave and growth rate is derived incorporating both pondermotive and Ohmic heating effects. The growth rate and mode frequencies were evaluated based on existing dusty plasma parameters. It is found that the unstable collisional drift mode frequency increases and the growth rate decreases sharply with the relative density of negatively charged dust grains. Moreover, the collisional frequency has no effect on the unstable drift mode frequency. However, the increases in collisional frequency andmore »

On the spacecharge formation in a collisional magnetized electronegative plasma
The plasma sheath formation in the vicinity of a surrounding wall of magnetized plasma is studied in the presence of the electronegative ions and the positive ionneutral background collisions. Fluid equations are used to treat the plasma particles species. By using the Sagdeev potential, the influence of the collisions and the magnetic field on the Bohm criterion are investigated. The spacecharge profiles are obtained in the presence of a magnetic field in different collision frequencies as well as electronegative ions concentration. It is shown that the collision and the magnetic field raise a spacecharge peak, while the presence of themore » 
Propagation of surface waves on a semibounded quantum magnetized collisional plasma
The propagation of surface waves on a semibounded quantum plasma in the presence of the external magnetic field and collisional effects is investigated by using quantum magnetohydrodynamics model. A general analytical expression for the dispersion relation of surface waves is obtained by considering the boundary conditions. It is shown that, in some special cases, the obtained dispersion relation reduces to the results reported in previous works. It is also indicated that the quantum, external magnetic field and collisional effects can facilitate the propagation of surface waves on a semibounded plasma. In addition, it is found that the growth rate ofmore » 
Comment on “Propagation of surface waves on a semibounded quantum magnetized collisional plasma” [Phys. Plasmas 20, 122106 (2013)]
In a recent article [Niknam et al., Phys. Plasmas 20, 122106 (2013)], Niknam et al. investigated the propagation of TM surface waves on a semibounded quantum magnetized collisional plasma in the Faraday configuration (in this case, the magnetic field is parallel to the both of the plasma surface and direction of propagation). Here, we present a fresh look at the problem and show that TM surface waves cannot propagate on surface of the present system. We find in the Faraday configuration the surface waves acquire both TM and TE components due to the cyclotron motion of electrons. Therefore, the mainmore » 
Response to “Comment on ‘Propagation of surface waves on a semibounded quantum magnetized collisional plasma’” [Phys. Plasmas 23, 044701 (2016)]
We reply to the Comment of Moradi [Phys. Plasmas 23, 044701 (2016)] on our paper [Phys. Plasmas 20, 122106 (2013)]. It is shown that TM surface waves can propagate on the surface of a semibounded quantum magnetized collisional plasma in the Faraday configuration in the electrostatic limit. In addition, in the Faraday configuration, one can neglect the coupling of TM and TE modes in the two limiting cases of weak magnetic field (low cyclotron frequency) and strong magnetic field (high cyclotron frequency).
