THE MINIMUM-UNCERTAINTY SQUEEZED STATES FOR ATOMS
... The purpose of this paper is to construct the minimum-uncertainty squeezed states for quantum harmonic oscillators, which are important in these applications, in the most simple closed form. Our approach reveals the quantum numbers/integrals of motion of the squeezed states in terms of solution of c ...

Relations between Massive and Massless one
... A massive particle with spin j has 2j+1 one-particle states, such as the spin 3/2 9Be’s nuclei, whose magnetic quantum numbers are 3/2, 1/2, -1/2, -3/2. However, it is different about a particle with mass zero (for example photon). Photons’ helicity has only two values: 1,-1. Helicity zero is forbid ...
