Number-parity effect for confined fermions in one dimension
For $N$ spin-polarized fermions in a $1$-dimensional trap with strong attractive interactions an odd-even effect is found. The entanglement spectrum of the $1$-particle reduced density matrix of the system's ground state differs qualitatively for $N$ odd and $N$ even. Since this effect does not...
