Description
This talk will focus on qualitative properties of normalized ground states for a nonlinear Schrödinger equation with double-power nonlinearity. These ground states are characterized as energy minimizers under a fixed L^2-norm contraint. I will present recent results concerning their existence, and I will discuss their uniqueness in certain regimes of parameters. Joint work with Mathieu Lewin.
