Colloquium in Theoretical Physics
Professor Sven Åberg
Division of Mathematical Physics, LTH, Lund University
Friday, 20th May 2005, 13.30
Lecture hall (Sal) F, Sölvegatan 14
Quantum chaos is defined as the study of quantum versions of classically
chaotic systems. We start by introducing chaos in classical mechanics, and
then signatures of chaos in quantum mechanics. This is illustrated by
considering the hydrogen atom in a strong magnetic field. We then discuss
quantum chaos in interacting many-body systems, such as atomic nuclei and
quantum dots. What may cause quantum chaos in many-body systems, and what
is the relative role of the confining (or mean field) potential and the
two-body interaction? Specifically we shall consider a deformed quantum
dot, and rotating atomic nuclei. We finally discuss if the error in best
nuclear mass formulae is due to quantum chaos.
The Colloquia in Theoretical Physics are aimed for a general audience of
students, teachers and researchers interested in physics and the laws of
Nature. Coffee will be served after the Colloquium.
Everybody is welcome!
