Tests of physics beyond the Standard Model with single-electron ions
Vincent Debierre, Christoph H. Keitel, Zoltan Harman
A highly effective approach to the search for hypothetical new interactions through isotope shift spectroscopy of hydrogen-like ions is presented. A weighted difference of the g fa…
Radiative and photon-exchange corrections to New Physics contributions to energy levels in few-electron ions
Vincent Debierre, Natalia S. Oreshkina
The influence of hypothetical new interactions beyond the Standard Model on atomic spectra has attracted recent interest. In the present work, interelectronic photon-exchange corre…
Two-loop virtual light-by-light scattering corrections to the bound-electron factor
V. Debierre, B. Sikora, H. Cakir +4
A critical set of two-loop QED corrections to the factor of hydrogenlike ions is calculated without expansion in the nuclear binding field. These corrections are due to the pol…
Improved access to the fine-structure constant with the simplest atomic systems
H. Cakir, N. S. Oreshkina, I. A. Valuev +4
A means to extract the fine-structure constant from precision spectroscopic data on one-electron ions is presented. We show that in an appropriately weighted difference of the…
The factor of bound electrons as a test for physics beyond the Standard Model
V. Debierre, C. H. Keitel, Z. Harman
The use of high-precision measurements of the factor of few-electron ions and its isotope shifts is put forward as a probe for physics beyond the Standard Model. The contributi…
Long-range interactions of hydrogen atoms in excited states. III. nS-1S interactions for n >= 3
C. M. Adhikari, V. Debierre, U. D. Jentschura
The long-range interaction of excited neutral atoms has a number of interesting and surprising properties, such as the prevalence of long-range, oscillatory tails, and the emergenc…
