N2 - One-dimensional (1D) subwavelength atom arrays display multiply excited subradiant eigenstates which are reminiscent of free fermions. So far, these states have been associated with subradiant states with decay rates proportional to N-3, with N the number of atoms, which fundamentally prevents detection of their fermionic features by optical means.
