64. Probing the local dispersion of k-vectors in situ with a Bose-Einstein Condensate

The fine-structure constant $\alpha$ can be determined with high precision through measurements of the ratio $h/m$ between the Planck constant and the atomic mass using atom interferometry. Our latest determination of $\alpha$ has achieved a relative uncertainty of $8.1\times 10^{-11}$, establishing recoil measurements as a cornerstone of precision metrology and tests of the Standard Model....

53. Resolving the doublet-quartet separation in neutral boron

Accurate energy intervals in light open-shell atoms remain a stringent test for both precision spectroscopy and ab initio electronic-structure theory. One of the most persistent benchmarks is neutral boron: the separation between the ground $^2P^o$ state and the lowest $^4P^e$ quartet, together with the quartet fine structure, has resisted definitive theoretical--experimental reconciliation...

32. Probing Bound State QED above the Schwinger Limit with high precision kaonic atoms measurements

Francesco Clozza (INFN-LNF & Università degli Studi di Roma "Tor Vergata")

Exotic atoms constitute a unique platform to explore fundamental interactions and symmetries. In particular, kaonic atoms are a great tool to investigate quantum electrodynamics in extreme electromagnetic fields. While conventionally exploited to investigate low-energy QCD through hadronic shifts and widths, kaonic atoms also offer a unique opportunity to probe bound-state QED (BSQED) in a...
