Duality of reduced density matrices and their eigenvalues
<p style="text-align:justify;">For states of quantum systems of N particles with harmonic interactions we prove that each reduced density matrix ρ obeys a duality condition. This condition implies duality relations for the eigenvalues λk of ρ and relates a harmonic model with length...
