Kvantový kroužek ONLINE: Sylwia Kondej - Optimization problem for quantum system with star-shaped po
01 Dec 2020 14:45
Srdečně vás zveme na další seminář v rámci Kvantového kroužku ONLINE. Prostřednictvím platformy Zoom bude hovořit Sylwia Kondej (University of Zielona Gora) na téma Optimization problem for quantum system with star-shaped potential. Seminář se koná v úterý 1. 11. 2020 od 14.45 hod. Zoom-ové souřadnice, které vám umožní se semináře zúčastnit, najdete na webu Kvantového kroužku.
Abstract:
We discuss the spectral properties of singular Schroeodinger operators in three dimensions with the interaction supported by an equilateral 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. The results discussed in the talk are the joint work with Pavel Exner.
