"Generalized Pauli Constraints
and Their Physical Relevance"
By
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.
