Scattering and uniform in time error estimates for splitting method in NLS
Rémi Carles, Chunmei Su
We consider the nonlinear Schr{ö}dinger equation with a defocusing nonlinearity which is mass-(super)critical and energy-subcritical. We prove uniform in time error estimates for t…

Nonuniqueness and nonlinear instability of Gaussons under repulsive harmonic potential
Rémi Carles, Chunmei Su
We consider the Schr{ö}dinger equation with a nondispersive logarithmic nonlinearity and a repulsive harmonic potential. For a suitable range of the coefficients, there exist two p…

Various variational approximations of quantum dynamics
Caroline Lasser, Chunmei Su
We investigate variational principles for the approximation of quantum dynamics that apply for approximation manifolds that do not have complex linear tangent spaces. The first one…
