Soliton Solutions of Integrable Hierarchies and Coulomb Plasmas

چکیده
Some direct relations between soliton solutions of integrable hierarchies and thermodynamical quantities of the Coulomb plasmas on the plane are revealed. We find that certain soliton solutions of the Kadomtsev-Petviashvili (KP) and B-type KP (BKP) hierarchies describe two-dimensional one or two component plasmas at special boundary conditions and fixed temperatures. It is shown that different reductions of integrable hierarchies describe one (two) component plasmas or dipole gases on one-dimensional submanifolds embedded in the two-dimensional space. We demonstrate application of the methods of soliton theory to statistical mechanics of such systems.

Solution and stability analysis of coupled nonlinear Schrodinger equations
We consider a new type of integrable coupled nonlinear Schrodinger (CNLS)equations proposed by our self [submitted to Phys. Plasmas (2011)]. The explicitform of soliton solutions are derived using the Hirota's bilinear method.We show that the parameters in the CNLS equations only determine the regionsfor the existence of bright and dark soliton solutions. Finally, throughthe linear stability an...
متن کاملNonlinearizing linear equations to integrable systems including new hierarchies with source terms
Reverse to linearization, we propose a nonlinearization scheme of linear systems for generating integrable equations, based on a simple scaling dimensional argument. This yields together with well known integrable systems, new hierarchies of integrable equations with source terms, allowing exact n-soliton solutions. The novelty of such sources is that they can be deformed recursively by going t...
متن کاملThe structures underlying soliton solutions in integrable hierarchies
We point out that a common feature of integrable hierarchies presenting soliton solutions is the existence of some special “vacuum solutions” such that the Lax operators evaluated on them, lie in some abelian subalgebra of the associated Kac-Moody algebra. The soliton solutions are constructed out of those “vacuum solitons” by the dressing transformation procedure. This talk is concerned with t...

To start with, having employed transformation wave, some nonlinear partial differential equations have been converted into an ODE. Then, using the infinite series method for equations with similar linear part, the researchers have earned the exact soliton solutions of the selected equations. It is required to state that the infinite series method is a well-organized method for obtaining exact s...
متن کاملNew analytical soliton type solutions for double layers structure model of extended KdV equation
In this present study the double layers structure model of extended Korteweg-de Vries(K-dV) equation will be obtained with the help of the reductive perturbation method, which admits a double layer structure in current plasma model. Then by using of new analytical method we obtain the new exact solitary wave solutions of this equation. Double layer is a structure in plasma and consists of two p...
