Query: Geometrical Representation of Angular Momentum Coherence and Squeezing   A simple, and elegant geometrical representation is developed to describe the
concept of coherence and squeezing for angular momentum operators. Angular
momentum squeezed states were obtained by applying Bogoliubov transformation on
the angular momentum coherent states in Schwinger representation [Phys. Rev.
{\bf{A 51}} (1995)]. We present the geometrical phase space description of
angular momentum coherent and squeezed states and relate with the harmonic
oscillator. The unique feature of our geometric representation is the
portraying of the expectation values of the angular momentum components
accompanied by their uncertainties. The bosonic representation of the angular
momentum coherent and squeezed states is compared with the conventional one
mentioning the advantages of this representation of angular momentum in context
of coherence and squeezing. Extension of our work on single mode squeezing to
double mode squeezing is presented and compared with the single mode one. We
also point out the possible applications of the geometrical representation in
analyzing the accuracy of interferometers and in studying the behavior,
dynamics of an ensemble of quantum-mechanical two-level systems and its
interaction with radiation.
