I have recently proposed a slight non-relativistic modification of the Newton law of universal gravitation [1,2]. Accordingly, the 1/r Newton
field is following the motion of the source with a certain
laziness characterized by the delay time τ_G. The background motivation came from
quantum foundational
speculations [3,4] yielding an estimate τ_G ∼ 1ms. Surprisingly, in the simplest model...

Quantum electrodynamic (QED) effects in strong fields can be scrutinized to high precision in Penning trap experiments: a recent measurement yielded a value
for the $g$-factor of hydrogenlike silicon with a $5 \times 10^{-10}$ fractional uncertainty, allowing to test certain higher-order QED corrections for the
first time [1]. The measured $g$-factor is in excellent agreement with the...

We establish the existence of spin-statistic selection rules (SSSRs) for multiphoton transitions with equal photons in atomic systems. These selection rules are similar to those for systems of many equivalent electrons in atomic theory. The latter are a direct consequence of the Pauli exclusion principle. In this sense, the SSSRs play the role of the exclusion principle for photons: they...

Understanding the ionization process during atomic collisions is fundamental both from the experimental and theoretical points of view. Ionization by positron impact has also been extensively studied in recent decades. In most cases noble gas atoms were used as the target For designing new experiments, such as production of antimatter, ionization cross sections for any other atoms are also...
