We prove that for non-relativistic two-body systems the order of energy levels with the same principal Coulomb quantum number is controlled by the sign of the laplacian of the (spherically symmetric) potential. If it is positive, the levels with larger angular momentum have lower energy. If it...

We have completed theoretical predictions for positronium energy levels through order mα6 by the calculation of the spin independent radiative recoil correction. This contribution is significant and amounts to 10.64 MHz for the 1S state. We further perform a detailed comparison of theoretical predicti...
Contributions to the energy levels in light muonic atoms and, in particular, to the Lamb shift fall into a few well-distinguished classes. The related diagrams are calculated using different approaches. In particular, there is a specific type of nonrelativistic (NR) contribution. Here, we conside...
Interaction energy in smallN-particle systems and the permutation group The distribution of energy levels of an N-identical-particle system among the irreducible representations of the permutation group is examined for a "spin-...

There are dark secrets that have an annoying tendency to crawl back into the light, escaping oblivion. But there is also Sarah Pennington, the most skilled agent of the ever-watching Secret Order, who is there to face them.
and several characteristic AE phenomena (i.e., dramatic increase in dominant frequency, AE energy, and hit rate, the AE event with a high energy level, and the through-going distribution of the AE events with intermediate energy levels) were statistically analyzed before the failure occurred. It...
For example, an electric field can shift atomic energy levels and thus “time dilate” a clock based on atomic transitions. Therefore, one can produce a state analogous to (4) without using gravity. However, only gravity can alter the relative ordering of events independently of the nature of...
