S squeezing and correlation of pure spin 32 system

الملخص EN

The notion of spin squeezing involves a reduction in the uncertainty of a components of spin vector below a certain limit.

This aspect has been studied earlier by Kitagawa, Udea [1], Mallesh [2], Jian Ma, Xiaoguang Wang [3] and Keyu Xia, Jason Twamley [4] for spin state.

In this paper we extended to the higher spin 3/2 system, using three spin 1/2 system and study it’s squeezing behavior.

A discussion of spin-spin correlations and their link with squeezing will be studied.

It will be shown that the existence of correlations is only a necessary condition for squeezing to be present.
