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…
Density Functional Theory Study of Th-doped LiCAF and LiSAF for Nuclear Clock Applications
Martin Pimon, Tobias Kirschbaum, Thorsten Schumm +2
Thorium-doped LiCaAlF and LiSrAlF (Th:LiCAF and Th:LiSAF) are promising crystals for a solid-state nuclear clock based on the 8 eV transition in Th; however, their…
Electronic Bridge processes in Th-doped LiCAF and LiSAF
Tobias Kirschbaum, Martin Pimon, Andreas Grüneis +2
Electronic bridge mechanisms driving the Th nuclear clock transition in the vacuum-ultraviolet-transparent crystals Th:LiCAF (LiCaAlF) and Th:LiSAF (LiS…
Probing Nuclear Excitation by Electron Capture in an Electron Beam Ion Trap with Non-destructive Isomer Detection via Precision Mass Spectrometry
Bingsheng Tu, Nan Xue, Jialin Liu +10
Nuclear excitation by electron capture (NEEC) is an important nuclear excitation mechanism which still lacks conclusive experimental verification. This is primarily attributed to s…
