Resumen:
Numerical and analytical results for the squeezing factor, æ2, in a pseudo-spin s - 1 / 2 chain. The open chain is composed by N two-level atoms with site-dependent interactions. The time evolution of the squeezing factor is studied, as well as its dependence on the number of atoms and on the interactions. It is found that long-range interactions may optimize the degree of spin squeezing.
