Coherence and squeezing in superpositions of spin coherent states

[摘要] We consider the superpositions of spin coherent states and study the coherence properties and spin squeezing in these states. The spin squeezing is examined using a new version of spectroscopic squeezing criteria. The results show that the antibuching effect can be enhanced and spin squeezing can be generated in the superpositions of two spin coherent states. (C) 2001 Published by Elsevier Science BN.
