| Apr 30, 2019 at 8:00 | comment | added | David Bar Moshe | @SachinKumar A famous theorem by von Neumann and Wigner states that in the space of Hermitian matrices, the subspace of matrices having at least one degenerate eigenvalue has a codimension 2, i.e., they are very rare. This theorem is explained clearly in the following review by Pflaum euclid.colorado.edu/~pflaum/teaching/Fall17/… The Hamiltonians of heavy nuclei are very complicated; thus it should generically satisfy this rule. | |

@David, in a Article by Guhr says- the Wigner surmise excludes degeneracies, p(0) = 0, the levels repel each other. This is only possible if they are correlated, could you pl explain.
