“…Moreover, the geometry of most laboratory devices is cylindrical or spherical but not of planar configuration. In the past decade, the MI studies 6,12,14,15 of the DA waves were also mainly limited to the Maxwellian distribution. However, the space plasma observations, for example, in the Earth's bow-shock, in the upper ionosphere of Mars, and in the vicinity of the Moon, 16 clearly indicate the presence of ions and electrons, which depart from the Maxwellian distribution.…”

“…[25][26][27][28][29] On the other hand, it has been found both theoretically and experimentally that there are negative ions, which occur in many space and laboratory plasma. [30][31][32][33][34][35] The existence of such dust ion acoustic waves with a higher phase speed has been later experimentally confirmed by Barkan et al 36 in dusty plasmas. The linear properties of the dust ion acoustic waves are well understood both theoretically and experimentally.…”

Plasmas Damping solitary wave in dusty plasma is studied by considering the collision effect between dust grains and ions. It can be described by a KdV type equation in which a damping term of u 2 exist. It is found that both the amplitude and propagation velocity of the solitary wave decrease with time exponentially. Our results are compared with another KdV type equation with the damping term of u. It is noted that the damping rate of the KdV type equation with the damping term of u 2 is larger than that with the term of u. It is found that the damping rate is proportional to the collision frequency between dust grains and ions. V C 2012 American Institute of Physics.

“…In general, most of the existing research on dusty plasmas has focused attention only on mono-sized dusty plasma (Mamun 1998(Mamun , 2008Ghosh et al 2001;El-Labany et al 2007a;Pakzad 2009;Wang et al 2011). Actually, the dust particles have many different sizes both in the space environment and in laboratory experiments (Chow et al 1993;Meuris 1997).…”

“…Moreover, the head-on collision between two solitary waves propagating in different plasma models in opposite direction was investigated by many investigators using the extended Poincaré-LighthillKuo (PLK) method (Xue 2004;Liang et al 2009;El-Labany et al 2010a). For example, the head-on collision between DASWs in an unmagnetized (Xue 2004) and magnetized (Xue 2006) dusty plasma have been studied. Xue (2004Xue ( , 2006 found that the dust charge variation, the magnitude and the obliqueness of the external magnetic field significantly modify the phase shifts.…”

The head-on collision between two quantum dust-acoustic solitary waves (QDASWs) in ultradense astrophysical objects has been investigated theoretically using the extended Poincaré-Lighthill-Kuo (PLK) method. The Korteweg-de Vries equations and the analytical phase shifts after the head-on collision of the two QDASWs in quantum dusty plasmas are obtained. Numerically, the obtained results demonstrate that the dust size distribution, the quantum corrections of diffraction and the temperatures of electrons and ions have strong effects on the nature of the phase shifts and the trajectories of the two QDASWs after collision.
