Bulk spectra and the non-Hermitian skin effect in systems with long-range couplings
Jonathan Sturm, Pia KreÃ, Pia Kreß +2
To achieve translational symmetry for the computation of the band structure of a lattice model, one can either consider an infinite lattice or impose periodic boundary conditions (…

Polarization-dependent topology in quantum emitter chains
Jonathan Sturm, Adriana Pálffy
The role of polarization in the topology of quantum emitter chains is investigated theoretically, whereby "polarization" refers to the transition dipole moments of the emitters. We…

Exploring Topological Effects in Thin-Film X-Ray Cavities
Hanns Zimmermann, Jonathan Sturm, Ion Cosma Fulga +2
Quantum control of single x-ray photons can be achieved using thin-film nanostructure cavities with embedded layers of resonant nuclei. Here, we design and theoretically investigat…
