Beyond geometric symmetry: Broadband linear relations in wave scattering
Malte Röntgen, Sucui Luo, Xuelong Chen +4
The design and control of wave scattering, that is, of the reflection and transmission parameters of a device, is of ubiquitous importance. These parameters generally change with v…
State Transfer in Latent-Symmetric Networks
Jonas Himmel, Max Ehrhardt, Matthias Heinrich +5
The transport of quantum states is a crucial aspect of information processing systems, facilitating operations such as quantum key distribution and inter-component communication wi…
Eigenmodes of latent-symmetric quantum photonic networks
Jonas Himmel, Max Ehrhardt, Matthias Heinrich +3
We investigate the impact of latent symmetries on the dynamics of photonic systems and their eigenmodes. Residing solely within the eigenspectral domain, latent symmetries are not…
Graph-theoretical approach to the eigenvalue spectrum of perturbed higher-order exceptional points
Daniel Grom, Julius Kullig, Malte Röntgen +1
Exceptional points are special degeneracy points in parameter space that can arise in (effective) non-Hermitian Hamiltonians describing open quantum and wave systems. At an n-th or…
Flat bands by latent symmetry
C. V. Morfonios, M. Röntgen, M. Pyzh +1
Flat energy bands of model lattice Hamiltonians provide a key ingredient in designing dispersionless wave excitations and have become a versatile platform to study various aspects…
Transfer efficiency enhancement and eigenstate properties in locally symmetric disordered finite chains
C. V. Morfonios, M. Röntgen, F. K. Diakonos +1
The impact of local reflection symmetry on wave localization and transport within finite disordered chains is investigated. Local symmetries thereby play the role of a spatial corr…
