Abstract

We numerically find out the spectrum of the 33 spin 11 Dirac operators found in~\cite{ApbPP}. We give an analytic and numerical proof that they are unitarily inequivalent. Since these operators come paired with an anticommuting chirality operator, we find their spectrums to resemble those of fermions with positive and negative eigenvalues along with a number of zero modes. We give a method to count the number of zero modes which can be extended to higher spins on SF2S_F^2. An universal relation between the energy eigenvalues of the spin 1 Dirac operator and their multiplicities is found. This helps us predict the energy eigenvalues for an arbitrarily large cut-off LL, a problem which is computationally difficult to handle.
