Optical quantum memories are key elements in modern quantum technologies to reliably
store and retrieve quantum information. At present, they are conceptually limited to the …

Although electrons and photons are the most widely researched elementary particles, their
interactions outside of the confines of a material are not yet fully explored. Here, we report …

Thin-film cavities containing layers of Mössbauer nuclei have been demonstrated to be a
rich platform for x-ray quantum optics. At low excitation, these systems can be described by …

Up to now, experiments involving Mössbauer nuclei have been restricted to the low-
excitation regime (LER). The reason for this is the narrow spectral linewidth of the nuclei …

Time has a central role in physics. Entering the realm of ultrashort timescales is always an
exciting endeavour. Two recent publications, in Nature 1 and Science Advances 2, report …

Owing to their extremely narrow line-widths and exceptional coherence properties,
Mössbauer nuclei form a promising platform for quantum optics, spectroscopy, and …

To meet the increasing demand for high-energy (Joule-level) few-cycle pulses in strong-field
physics research, coherent beam combining (CBC) presents an effective method to further …
