Variation of fundamental constants from Big Bang to atomic clocks |
Abstract _ |
Theories unifying gravity with other interactions suggest a possibility of space-time variation of the fundamental constants. I present a review of recent works devoted to the variation of the fine structure constant alpha, strong interaction and fundamental masses.There are some hints for the variation in quasar absorption spectra, Big Bang nucleosynthesis, and Oklo natural nuclear reactor data. A very promising method to search for the variation of the fundamental constants consists in comparison of different atomic clocks. Huge enhancement of the variation effects happens in transition between accidentally degenerate atomic and molecular energy levels. |
