Spin-selective coherent light scattering from ion crystals
Maurizio Verde, Ansgar Schaefer, Benjamin Zenz +5
We study coherent light scattering from linear crystals with up to twelve ions, acting as single photon emitters. Light-scattering is induced by two-photon laser…
On-sky demonstration of an ultra-fast intensity interferometry instrument utilizing hybrid single photon counting detectors
Verena G. Leopold, Sebastian Karl, Jean-Pierre Rivet +1
Intensity interferometry is a reemerging astronomical technique for performing high angular resolution studies at visible wavelengths, benefiting immensely from the recent improvem…
Multi-Path and Multi-Particle Tests of Complex vs. Hyper-Complex Quantum Theory
Ece İpek Saruhan, Joachim von Zanthier, Marc-Oliver Pleinert
The axioms of quantum mechanics provide limited information regarding the structure of the Hilbert space, such as the underlying number system. The latter is generally regarded as…
Hanbury Brown and Twiss interference of electrons in free space from independent needle tip sources
Anton Classen, Raul Corrêa, Florian Fleischmann +4
We investigate two-electron interference in free space using two laser-triggered needle tips as independent electron sources, a fermionic realisation of the landmark Hanbury Brown…
