"Generalized Pauli Constraints and Their Physical Relevance"
Abstract: The Pauli exclusion principle has a tremendous impact on the properties and the behavior of most fermionic quantum systems. By a recent break-through in mathematical physics even stronger restrictions on fermionic occupation numbers have been revealed. By studying a system of N interacting fermions confined by a harmonic trap we found ground state occupation numbers which are lying very close to (but not exactly on) the boundary of the allowed region. We explain the physical relevance of this quasipinning effect and provide first insights into the mechanism behind it. Our findings also suggest a naturalgeneralization of the Hartree-Fock optimization method.
