Backreaction and the Covariant Formalism of General Relativity
... Because set in this way the model gives us predictions that are in conflict with late time observations, and these observations are beyond doubt, at least one of the three assumptions must be wrong. Usually in the framework of the ΛCDM model the agreement with data is restored by introducing a term ...

Proposed search for an electric-dipole moment using laser
... The freely falling atoms are first spin polarized using a beam of right-circularly polarized (σ + ) light at 556 nm. The laser is tuned to the F = 1/2 → F ′ = 1/2 transition. Since this is a closed transition, atoms are optically pumped into the mF = +1/2 sublevel of the ground state. The atoms then ...
