Non-Hermitian propagation of Hagedorn wavepackets
Caroline Lasser, Roman Schubert, Stephanie Troppmann
We investigate the time evolution of Hagedorn wavepackets by non-Hermitian quadratic Hamiltonians. We state a direct connection between coherent states and Lagrangian frames. For t…
An invariant class of wave packets for the Wigner transform
Helge Dietert, Johannes Keller, Stephanie Troppmann
Generalised Hagedorn wave packets appear as exact solutions of Schrödinger equations with quadratic, possibly complex, potential, and are given by a polynomial times a Gaussian. We…
Hagedorn wavepackets in time-frequency and phase space
Caroline Lasser, Stephanie Troppmann
The Hermite functions are an orthonormalbasis of the space of square integrable functions with favourable approximation properties. Allowing for a flexible localization in position…
