We would like to invite you to the seminar of Quantum Circle ONLINE. Through the Zoom platform will speak Hynek Kovařík (Universitá degli studi di Brescia) on Absence of positive eigenvalues of magnetic Schrödinger operators. The seminar takes place on Tuesday, December 15, 2020 from 2.45 pm. The Zoom link, which will allow you to participate in the seminar, can be found on the Quantum Circle website.

We study sufficient conditions for the absence of positive eigenvalues of magnetic Schrödinger operators in Rn. 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. The talk is based on a joint work with Silvana Avramska-Lukarska and Dirk Hundertmark.
