Quantum tetrahedron volume and angle eigenvalues

by David Horgan.

Enter the four J values into the input boxes. The values k range from kmin to kmax in integer steps. The dimension d of the Hilbert space H4, d = kmax - kmin + 1. we have kmin = max(|j1-j2|,|j3 -j4|)and kmax = min(j1+j2,j3 +j4). The the dimension of the hilbert space is given by d = kmax -kmin + 1. The volume matrix V^2 =M = 2/9(real antisymmetrix matrix). The spins must satisfy (j1+j2)<= (j3+j4)- the triangle inequality.
