Phys. Rev. Lett. 85, 4016–4019 (2000)Geometric Chaoticity Leads to Ordered Spectra for Randomly Interacting FermionsReceived 8 May 2000; published in the issue dated 6 November 2000 A rotationally invariant random interaction ensemble was realized in a single- j fermion model. A statistical approach reveals the random coupling of individual angular momenta as a source for the empirically known dominance of ground states with zero and maximum spin. The interpretation is supported by the structure of the ground state wave functions. © 2000 The American Physical Society URL:
