Abstract (English)

In this thesis, we address the long-standing question of time-reversal protocols for the quantum mechanical wave function for continuous degrees of freedom. We propose two new mechanisms - quantum time mirrors - one for two-band systems, the other one for systems described by the nonlinear Schrödinger equation like Bose-Einstein condensates. In both cases, a homogeneous pulse is applied to the ...


Translation of the abstract (German)

In dieser Arbeit behandeln wir die seit langem bestehende Frage ob Zeitumkehr-Protokolle für die quantenmechanische Wellenfunktion von kontinuierlichen Freiheitsgraden möglich sind. Es werden zwei neue Mechanismen vorgeschlagen, sogenannte Quanten-Zeit-Spiegel, einerseits für Zweibandsysteme und andererseits für Systeme, die durch die nichtlineare Schrödingergleichung beschrieben werden, wie zum ...
