Dynamical approximations for composite quantum systems: Assessment of error estimates for a separable ansatz
Irene Burghardt, Rémi Carles, Clotilde Fermanian Kammerer +2
Numerical studies are presented to assess error estimates for a separable (Hartree) approximation for dynamically evolving composite quantum systems which exhibit distinct scales d…

An Error Bound for the Time-Sliced Thawed Gaussian Propagation Method
Paul Bergold, Caroline Lasser
We study the time-sliced thawed Gaussian propagation method, which was recently proposed for solving the time-dependent Schrödinger equation. We introduce a triplet of quadrature-b…

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…
