[institut] Reminder - seminar Lab.At.Coll.Proc.: R.G. Nazmitdinov, 25. Sep. 2019.

[Nenad Simonovic]

Dear colleagues,

You are cordially invited to attend a seminar organized by the 
Laboratory for Atomic Collision Processes which will be held on 
Wednesday, 25. September 2019 (today) at 12:00 in the library reading 
room "Dr. Dragan Popovic" of the Institute of Physics Belgrade. The talk 
entitled:

Symmetry phenomena in finite quantum systems: periodic orbits and 
quantum degeneracy

will be given by:

R. G. Nazmitdinov,
Bogoliubov Laboratory of Theoretical Physics,
Joint Institute for Nuclear Research, Dubna, Russia

Abstract:

We discuss symmetry effects produced by interplay of regular and chaotic 
dynamics of particles confined by effective potentials of various shapes 
in finite quantum systems. It is demonstrated that dynamical symmetries 
emerging from this interplay in classical and quantum systems are 
related to existence of conserved quantities of the dynamics and 
integrability. Important role of these symmetries are illustrated on a 
broad class of mesoscopic systems that include octupole deformed many 
body systems such as nuclei and clusters, and quantum dots in a magnetic 
field (see for a review [1]).
