Magnetic ring chains with vertex coupling of a preferred orientation

Marzieh Baradaran, Pavel Exner, Jiri Lipovsky

We discuss spectral properties of an periodic quantum graph consisting of an array of rings coupled either tightly or loosely through connecting links, assuming that the vertex cou…

Application of topological resonances in experimental investigation of a Fermi golden rule in microwave networks

Michał Ławniczak, Jiří Lipovský, Małgorzata Białous +1

We investigate experimentally a Fermi golden rule in two-edge and five-edge microwave networks with preserved time reversal invariance. A Fermi golden rule gives rates of decay of…

Topological bulk-edge effects in quantum graph transport

Pavel Exner, Jiri Lipovsky

We examine quantum transport in periodic quantum graphs with a vertex coupling non-invariant with respect to time reversal. It is shown that the graph topology may play a decisive…

The determinant of one-dimensional polyharmonic operators of arbitrary order

Pedro Freitas, Jiří Lipovský

We obtain an explicit expression for the regularised spectral determinant of the polyharmonic operator on with Dirichlet boundary conditi…

Spectral asymptotics of the Laplacian on Platonic solids graphs

Pavel Exner, Jiri Lipovsky

We investigate the high-energy eigenvalue asymptotics quantum graphs consisting of the vertices and edges of the five Platonic solids considering two different types of the vertex…

Non-Weyl Microwave Graphs

Michał Ławniczak, Jiří Lipovský, Leszek Sirko

One of the most important characteristics of a quantum graph is the average density of resonances, , where denotes the length of the graph. Th…
