Optical transitions in highly-charged californium ions with high sensitivity to variation of the fine-structure constant
Optical transitions highly-charged californium ions variation of the fine-structure constant Atomic Physics

We study electronic transitions in highly-charged Cf ions that are within the frequency range of optical lasers and have very high sensitivity to potential variations in the fine-structure constant, a...

Electrons in graphene behave like Dirac fermions, permitting phenomena from high energy
physics to be studied in a solid state setting. A key question is whether or not these Fermions are critically ...
Variation of the fine-structure constant from the de Sitter invariant special relativity
