Fig. 3: The level spectrum and corresponding wave functions of one isolated trimer.
From: Fractional and composite excitations of antiferromagnetic quantum spin trimer chains
The second column lists the wave functions in the spin-z basis, while the third column presents the spin structures using a basis of singlets (gray ovals and rounded shapes), zero-magnetization triplets (gray square shapes), and unpaired spins (arrows). The rightmost column lists the total spin quantum number S and magnetic quantum number M.
