Abstract (English)

The thesis addresses the fundamental interplay between indistinguishability and interactions in few- and many-body quantum systems, treated in two separate approaches, both analytic in nature, using semiclassical methods. The few-body sector, considering a strictly fixed number of particles, is addressed within the framework of first quantization. By sticking to descriptions as (micro-)canonical ...

Translation of the abstract (German)

Thema dieser Arbeit ist das fundamentale Zwischenspiel von Ununterscheidbarkeit und Wechselwirkungen in Wenig- und Vielteilchenquantensystemen. Zweier konträrer Situationen, die in separaten Ansätzen behandelt werden, die beide analytischer Natur sind und sich semiklassischer Methoden bedienen. Für Wenigteilchensysteme wird eine Beschreibung in erster Quantisierung herangezogen, bei der die ...
