DESCRIPTION:Title: <a href="https://researchseminars.org/talk/qc_seminar/5
 /">Absence of positive eigenvalues of magnetic Schroedinger operators</a>\
 nby Hynek Kovarik (Università degli studi di Brescia) as part of Quantum 
 Circle\n\n\nAbstract\nWe study sufficient conditions for the absence of po
 sitive eigenvalues of magnetic Schroedinger operators in R^n. In our main 
 result we prove the absence of eigenvalues above certain threshold energy 
 which depends explicitly on the magnetic and electric field. A comparison 
 with the examples of Miller-Simon shows that our result is sharp as far as
  the decay of the magnetic field is concerned.\nThe talk is based on a joi
 nt work with Silvana Avramska-Lukarska and Dirk Hundertmark.\n
