Spectral analysis of a class of Schroedinger operators exhibiting a parameter-dependent spectral transition

Diana Barseghyan, Pavel Exner, Andrii Khrabustovskyi +1

We analyze two-dimensional Schrödinger operators with the potential $∣ x y ∣^{p} - λ (x^{2} + y^{2})^{p / (p + 2)}$ where $p \geq 1$ and $λ \geq 0$ , which exhibit an abrupt change of its spectral prop…

Semiclassical bounds in magnetic bottles

Diana Barseghyan, Pavel Exner, Hynek Kovarik +1

The aim of the paper is to derive spectral estimates into several classes of magnetic systems. They include three-dimensional regions with Dirichlet boundary as well as a particle…
