Precision Tests of QED in Strong Fields and Nuclear Contributions

1995
The most simple of all atoms is hydrogen. One might imagine that its fundamental structure should allow for a theoretical description of the hydrogen spectrum at least as accurate as given by experiment. But as a matter of fact theory could not meet this requirement. E.

Accurate tests of QED with precision spectroscopy of molecular deuterium

2022
Molecular hydrogen, in the view of its simplicity, is well suited for testing quantum electrodynamics (QED) for moleculesas well as for searching for new physics beyond the standard model such as new forces or extra dimensions. Furthermore,molecular hydrogen possesses a wide structure of ultranarrow rovibrational transitions with different ...

QED precision studies in kaonic atoms with SIDDHARTA-2

Il Nuovo Cimento C
Kaonic atoms, where a negatively charged kaon replaces an electron, provide a unique system for precision studies of bound-state and strong-field quantum electrodynamics (QED). The SIDDHARTA-2 experiment at the DA $ \Phi$NE at INFN-LNF collider performs high-resolution X-ray spectroscopy of these systems using Silicon Drift Detectors.

Simulating and probing many-body quantum states in waveguide-QED systems with giant atoms

Physical Review A
Waveguide quantum electrodynamics (wQED) with giant atoms provides a distinctive opportunity to study one-dimensional (1D) coupled spin systems through its unique decoherence-free interactions.

Engineering entangled Schrödinger cat states of separated cavity modes in cavity QED

Physical Review A
We provide a scheme by utilizing a two-cavity setup to generate useful quantum mechanically entangled states of two cavity fields, which themselves are prepared in Schrodinger cat states.

High precision calculations and QED effects for two- and three-electron atoms

Physica Scripta, 1993
Essentially exact results can now be obtained for the nonrelativistic energy and lowest-order relativistic corrections of helium. A combination of variational calculations and asymptotic expansion methods covers the entire singly-excited spectrum.
