Symmetric angular momentum coupling, the quantum volume operator and the 7-spin network: a computational perspective
Dimitri Marinelli, Annalisa Marzuoli, Vincenzo Aquilanti +3
A unified vision of the symmetric coupling of angular momenta and of the quantum mechanical volume operator is illustrated. The focus is on the quantum mechanical angular momentum…
The screen representation of vector coupling coefficients or Wigner 3j symbols: exact computation and illustration of the asymptotic behavior
Ana Carla P. Bitencourt, Mirco Ragni, Robert G. Littlejohn +2
The Wigner symbols of the quantum angular momentum theory are related to the vector coupling or Clebsch-Gordan coefficients and to the Hahn and dual Hahn polynomials of the di…
The Screen representation of spin networks. Images of 6j symbols and semiclassical features
Mirco Ragni, Robert G. Littlejohn, Ana Carla P. Bitencourt +2
This article presents and discusses in detail the results of extensive exact calculations of the most basic ingredients of spin networks, the Racah coefficients (or Wigner 6j symbo…
The Screen representation of spin networks: 2D recurrence, eigenvalue equation for 6j symbols, geometric interpretation and Hamiltonian dynamics
Roger W. Anderson, Vincenzo Aquilanti, Ana Carla P. Bitencourt +2
This paper treats 6j symbols or their orthonormal forms as a function of two variables spanning a square manifold which we call the "screen". We show that this approach gives impor…
