  Preliminary work has been done in order to assess the perspectives of
metrology and fundamental physics atomic experiments at SYRTE and LKB in the
search for physics beyond the Standard Model and General Relativity. The first
studies we identified are currently ongoing with the Microscope mission and
with a Cs fountain clock. The latter brings significant improvement on the
proton-sector coefficient $\bar{c}_{TT}$ down to the $10^{-17}$ GeV level.
