Abstract: In this talk, I will consider the infinite ground states of Bose gases, defined as minimizers of the Gross-Pitaevskii energy functional under local perturbations. This leads to the nonlinear Gross-Pitaevskii equation at positive density, namely the solutions do not vanish at infinity. I will discuss several rigorous results and open questions regarding the phase transition from low to high density, where the constant solution ceases to be a ground state. This is joint work with Mathieu Lewin.
