Numerical work with Sagemath 11: Length eigenvalues in LQG

Whist working on A length operator for canonical quantum gravity by T. Thiemann I calculated the spectrum for the length operator using J1, J2 and J3 values for tri-, di- and j=1/2 values. I’ll be reworking this program and adding  interactive capability – then I’ll post it  at wiki.sagemath.org

sagemath on spectrum of length operator

As can be seen the length eigenvalues are of the order of the Planck length lp=1.61619926*10^-35
