Atomic Physics and Search for Variation of Fundamental Constants
4-5 p.m., Thursday, 9 March, 2006 .
of Physics Common Room
Two methods of search for variation of fundamental constants using atomic spectra will be considered in this talk. One is the analysis of quasar absorption spectra and another is laboratory experiments with atomic clocks.
Recent results for quasars do suggest that alpha might be smaller in early Universe, however the results are controversial so far.
the rates of different atomic clocks over long time interval is a very
promising method due to extremely high
The interpretation of all laboratory measurements and astronomical observations are based on calculations performed in our group.
