“…Linear aspects of the system have been considered in several studies (Iwamoto, 1993;Stewart and Laing, 1992;Zank and Greaves, 1995). Nonlinear processes have been a particularly rich area including such aspects as solitary waves (Dubinov et al, 2006;El-Shamy et al, 2010;Ghosh et al, 2012;Gordienko and Dubinov, 2008;Roy et al, 2012;Sabry, 2009), solitons (Cattaert and Kourakis, 2005;Sabry et al, 2009;Zank and Greaves, 1995), double layers (Alterkop et al, 2007;Mishra et al, 2007), collisionless reconnection processes (Bessho and Bhattacharjee, 2005;Hosseinpour and Vekstein, 2008) electrostatic and electromagnetic wave phenomena (El-Taibany and Mamun, 2012;Ghosh et al, 2012;Gordienko and Dubinov, 2007;Kourakis et al, 2007;Mushtaq and Khan, 2008), and vortices (Shukla et al, 2003).…”

In recent years, there has been a wealth of new science involving low-energy antimatter (i.e., positrons and antiprotons) at energies ranging from 10 2 to less than 10 −3 eV. Much of this progress has been driven by the development of new plasma-based techniques to accumulate, manipulate and deliver antiparticles for specific applications. This article focuses on the advances made in this area using positrons. However many of the resulting techniques are relevant to antiprotons as well. An overview is presented of relevant theory of single-component plasmas in electromagnetic traps. Methods are described to produce intense sources of positrons and to efficiently slow the typically energetic particles thus produced. Techniques are described to trap positrons efficiently and to cool and compress the resulting positron gases and plasmas. Finally, the procedures developed to deliver tailored pulses and beams (e.g., in intense, short bursts, or as quasi-monoenergetic continuous beams) for specific applications are reviewed. The status of development in specific application areas is also reviewed. One example is the formation of antihydrogen atoms for fundamental physics [e.g., tests of invariance under charge conjugation, parity inversion and time reversal (the CPT theorem), and studies of the interaction of gravity with antimatter]. Other applications discussed include atomic and materials physics studies and study of the electron-positron many-body system, including both classical electron-positron plasmas and the complementary quantum system in the form of Bose-condensed gases of positronium atoms. Areas of future promise are also discussed. The review concludes with a brief summary and a list of outstanding challenges.

A theory of ion sound waves in a dusty electron-positron-ion plasma is developed. It is shown in the linear approximation that periodic waves exist in a bounded range of parameters. The expression for the sound velocity is derived and the dependence of the velocity on the space charge of dust particles is analyzed. In the nonlinear theory, the general exact solution is obtained, which is then analyzed using the Bernoulli pseudopotential method. Particular solutions are obtained in the form of nonlinear periodic waves, large amplitude periodic waves (superlinear waves), and solitary compression and rarefaction waves (solitons).
