- Abstract
- We show the existence of new stationary solutions in the form of domain wall soliton in the nonlinear Schrodinger-Poisson equations describing the dynamics of quantum electron plasmas. It is found that the domain wall soliton exists at strong coupling constant regime and shows a different dynamical behavior in comparison with the previously found dark and gray solitons. The robustness and the conservation of the energy of the domain wall solitons is demonstrated by numerical simulations. (C) 2010 Elsevier B.V. All rights reserved.
