Bariş Öztop, Alexander Klyachko, Alexander S. Shumovsky
2007 Conference on Coherence and Quantum Optics   unpublished
We reformulate definition of spin squeezing and spin coherence in terms of the total variance in spin operators. We propose a new measure of spin squeezing. We show equivalence of spin squeezing and spin entanglement.
