Spin squeezing and precision probing with light and samples of atoms in the Gaussian description
Spin squeezing and precision probing with light and samples of atoms in the Gaussian description
We consider an ensemble of trapped atoms interacting with a continuous-wave laser field. For sufficiently polarized atoms and for a polarized light field, we may approximate the nonclassical components of the collective spin angular momentum operator for the atoms and the Stokes vectors of the field by effective position and …
