Abstract
We considered an application of a feedback loop to enhance the
self-organization of atoms in a cavity. Differently to the original setup,
we assumed the light leaking from the cavity was photo-detected and the
signal was used to appropriately adjust the atomic potential. It was shown
that no additional feedback-induced quantum noise was introduced into the
system. Numerical simulations performed in classical approximation showed
that the application of feedback weakened the requirement for the atom-field
coupling needed to observe the self-organization.
