We study, numerically, the charge neutral excitations (magnetorotons) in fractional quantum
Hall systems, concentrating on the two Jain states near quarter filling, ν= 2/7 and ν= 2/9, and …

We explore the scattering of waves in designed asymmetric one-dimensional waveguide
networks. We show that the reflection between two ports of an asymmetric network can be …

The propagation of wave trains resulting from a local external trigger inside a network
described by a metric graph is analyzed using quantum graph theory. The external trigger is …

We study experimentally the manifestation of non-Weyl graph behavior in open systems
using microwave networks. For this a coupling variation to the network is necessary, which …

Quantum graphs are ideally suited to studying the spectral statistics of chaotic systems.
Depending on the boundary conditions at the vertices, there are Neumann and Dirichlet …

The Wigner-Smith time-delay of flux conserving systems is a real quantity that measures
how long an excitation resides in an interaction region. The complex generalization of time …

This work deals with the scattering entropy of quantum graphs in many different
circumstances. We first consider the case of the Shannon entropy and then the Rényi and …
