Forschungsthemen
Probleme aus der statistischen Physik, insbesondere niedrigdimensionale
Systeme und lösbare Modelle. Themen der letzten Jahre:
Verschränkungseigenschaften
Untersuchung der Verschränkung in Vielteilchen-Quantensystemen
Dichtematrizen
Analyse und Anwendung eines neuartigen numerischen Verfahrens,
das für eindimensionale Quantensysteme extrem gute Resultate liefert.
Untersuchung der Dichtematritzen, auf denen es beruht, und ihrer
generellen Eigenschaften.
Nichtgleichgewichtsprobleme
Studium von Transportmodellen, bei denen sich klassische Teilchen
in einer Dimension statistisch bewegen, speziell im Hinblick auf
Phasenübergänge.
