Probing light forces on cold atoms by noise correlation spectroscopy
Probing light forces on cold atoms by noise correlation spectroscopy
Enhanced sensitivity in electromagnetically induced transparency (EIT) can be obtained by the use of noise correlation spectroscopy between the fields involved in the process. Here, we investigate EIT in a cold ($<1$ mK) rubidium vapor and demonstrate sensitivity to detect weak light-induced forces on the atoms. A theoretical model is …
