Traveling-wave solution to a nonlinear equation in semiconductors with strong spatial dispersion
A. B. Alshin, M. O. Korpusov, E. V. Yushkov Faculty of Physics, Moscow State University, Leninskie gory, Moscow, 119992, Russia
Abstract:
The third-order nonlinear differential equation $(u_{xx}-u)_t+u_{xxx}+uu_x=0$ is analyzed and compared with the Korteweg–de Vries equation $u_t+u_{xxx}-6uu_x=0$. Some integrals of motion for this equation are presented. The conditions are established under which a traveling wave is a solution to this equation.
Key words:
nonlinear Korteweg–de Vries equation, traveling-wave solutions, semiconductors with strong spatial dispersion.
