Phys. Rev. A 64, 042708 (2001) [11 pages]Rigid rotor in phase spaceReceived 18 April 2001; published 12 September 2001 Angular momentum is an important concept in physics, and its phase space properties are important in various applications. In this work a phase space analysis of angular momentum is made starting from its classical definition, and its quantum properties are obtained by imposing the uncertainty principle. The kinetic energy operator is derived, but its part have a different interpretation from that in the standard treatment. The rigid rotor is discussed and its phase space representation is shown. The true rigid rotor is defined and its phase space properties are also discussed. © 2001 The American Physical Society URL:
