    "abstract": "The traversal of an elliptically polarized optical field through a thermal\nvapour cell can give rise to a rotation of its polarization axis. This process,\nknown as polarization self-rotation (PSR), has been suggested as a mechanism\nfor producing squeezed light at atomic transition wavelengths. In this paper,\nwe show results of the characterization of PSR in isotopically enhanced\nRubidium-87 cells, performed in two independent laboratories. We observed that,\ncontrary to earlier work, the presence of atomic noise in the thermal vapour\noverwhelms the observation of squeezing. We present a theory that contains\natomic noise terms and show that a null result in squeezing is consistent with\nthis theory.",
