Search for Possible Variation of the Fine Structure Constant
Savely G. Karshenboim
Determination of the fine structure constant alpha and search for its possible variation are considered. We focus on a role of the fine structure constant in modern physics and dis…
Precision Study of Positronium: Testing Bound State QED Theory
Savely G. Karshenboim
As an unstable light pure leptonic system, positronium is a very specific probe atom to test bound state QED. In contrast to ordinary QED for free leptons, the bound state QED theo…
NMR spectroscopy of hydrogen deuteride and magnetic moments of deuteron and triton
Yurii I. Neronov, Savely G. Karshenboim
Magnetic moments of free and bound deuteron and triton are considered and new results for their magnetic moments (in units of that of the proton) and their g factors are presented.…
Time and Space Variation of Fundamental Constants: Motivation and Laboratory Search
Savely G. Karshenboim
Fundamental physical constants play important role in modern physics. Studies of their variation can open an interface to new physics. An overview of different approaches to a sear…
The g factor of proton
Savely G. Karshenboim, Vladimir G. Ivanov
We consider higher order corrections to the g factor of a bound proton in hydrogen atom and their consequences for a magnetic moment of free and bound proton and deuteron as well a…
Simple Atoms, Quantum Electrodynamics and Fundamental Constants
Savely G. Karshenboim
This review is devoted to precision physics of simple atoms. The atoms can essentially be described in the framework of quantum electrodynamics (QED), however, the energy levels ar…
High-Precision Optical Measurement of the 2S Hyperfine Interval in Atomic Hydrogen
N. Kolachevsky, M. Fischer, S. G. Karshenboim +1
We have applied an optical method to the measurement of the 2S hyperfine interval in atomic hydrogen. The interval has been measured by means of two-photon spectroscopy of the 1S-2…
