First Proof of Important Fermionic Theorem

For quite some time theorists have based their studies of fermionic systems' antisymmetry on the conjecture that for ground states there are only two domains which are created by a hypersurface or node. Professor Lubos Mitas provided the first analytical proof of this fundamental property. He further showed that for an arbitrary number of fermions there are only two nodal domains. These results are not only fundamentally important, in addition they have the potential of opening new channels for the Monte-Carlo methods which rely on the accuracy of fermion nodes. Reports of these discoveries of Professor Mitas and his group appear in two Phsyical Review Letters articles: PRL96, 130201 and PRL96, 240402.
