Approximations by graphs and emergence of global structures
Pavel Exner, Pavel Hejcik, Petr Seba
We study approximations of billiard systems by lattice graphs. It is demonstrated that under natural assumptions the graph wavefunctions approximate solutions of the Schroedinger e…

On relations between stable and Zeno dynamics in a leaky graph decay model
Pavel Exner, Takashi Ichinose, Sylwia Kondej
We use a caricature model of a system consisting of a quantum wire and a finite number of quantum dots, to discuss relation between the Zeno dynamics and the stable one which gover…

Sufficient conditions for the anti-Zeno effect
Pavel Exner
The ideal anti-Zeno effect means that a perpetual observation leads to an immediate disappearance of the unstable system. We present a straightforward way to derive sufficient cond…
