Squeezing in su(2) intelligent states

Angular momentum intelligent states are defined to satisfy \Delta J_x \Delta J_y = \frac{1}{2}|J_z| . They also share with angular momentum coherent states a number of features. In this paper we describe and illustrate the squeezing properties of angular momentum intelligent states. We analyze three classes of state: never squeezed, always squeezed and sometimes squeezed. Our conclusions are applicable for a broad range of definitions of the standard quantum limit for angular momentum systems.
