On the Exponential Decay of Magnetic Stark Resonances
Christian Ferrari, Hynek Kovarik
We study the time decay of magnetic Stark resonant states. As our main result we prove that for sufficiently large time these states decay exponentially with the rate given by the…

Magnetic strip waveguides
Pavel Exner, Hynek Kovarik
We analyze the spectrum of the "local" Iwatsuka model, i.e. a two-dimensional charged particle interacting with a magnetic field which is homogeneous outside a finite strip and tra…

Edge currents in the absence of edges
Pavel Exner, Alain Joye, Hynek Kovarik
We investigate a charged two-dimensional particle in a homogeneous magnetic field interacting with a periodic array of point obstacles. We show that while Landau levels remain to b…
