• We consider the initial-value problem for the cubic-quintic nonlinear Schrodinger equation $(i\partial_t+\Delta)\psi=\alpha_1 \psi-\alpha_{3}\vert \psi\vert^2 \psi+\alpha_5\vert \psi\vert^4 \psi$ in three spatial dimensions in the class of solutions with $|\psi(x)|\to c >0$ as $|x|\to\infty$. Here $\alpha_1$, $\alpha_3$, $\alpha_5$, and $c$ are such that $\psi(x)\equiv c$ is an energetically stable equilibrium solution to this equation. Normalizing the boundary condition to $\psi(x)\to 1$ as… CONTINUE READING
