Rotating Nonlinear States in Gross-Pitaevskii Equations
… directions: (1) Approximate solutions known as semiclassical wave packets to weakly nonlinear Schr\"odinger equations with rotation. (2) Existence and dynamical properties of rotating bound state solutions in both mass-subcritical and mass-supercritical regimes. The organization of the thesis is …

Conical Intersections and Avoided Crossings of Electronic Energy Levels
… crossings by considering a more general type of wave packet. We focus on the case of Schrödinger equation but our methods are general enough to be adapted to other systems with the geometric conditions therein. The motivation comes from the construction of surface hopping algorithms giving an …
