Workshop; Workshop on Quantum Simulations with Ultracold Atoms; 2012
The orientation and fluctuations of the total spin, in a system of N two-level atoms placed in a resonant cavity, and interacting with a single cavity mode and among themselves, are studied. The squeezing parameter of the system is calculated by using exact solutions. We calculated the time evolution of the populations of the atomic states and relate it with the spin-squeezing parameter. We studied the dependence of the squeezing factor with the number of atoms N and the initial conditions.
