DESCRIPTION:Title: <a href="https://researchseminars.org/talk/qc_seminar/3
 /">Optimization problem  for quantum system with star-shaped potential</a>
 \nby Sylwia Kondej (University of Zielona Gora) as part of Quantum Circle\
 n\n\nAbstract\nWe discuss the spectral properties of singular Schr\\"oding
 er operators in three dimensions with the interaction supported by an equi
 lateral star. Our main result concerns spectral optimization: we show that
  the principal eigenvalue is uniquely maximized when the arms are arranged
  in one of   the known five sharp configurations.\nThe results discussed i
 n the talk are the joint work with Pavel Exner.\n
