SEMINAR: R. G. Nazmitdinov

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 (tomorrow) at 12:00 in the library reading
room “Dr. Dragan Popovic” of the Institute of Physics Belgrade. The talk

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


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]).
