Figure 12: (a) Spectral weight, (b) spin deviation (b), and (c) average kinetic energy of mediated by magnons near neighbor transitions for 𝑔 1 = 0 (diamonds) and 𝑔 1 = 0 . 5 𝑔 (crosses). Other parameters are 𝐽 / 𝑡 = 0 . 4 , 𝜔 0 / 𝑡 = 0 . 2 , 𝑡 = − 0 . 5 𝑡 , 𝑡 = 0 . 4 𝑡 , and 𝑁 = 4 × 4 = 1 6 . Critical 𝜆 𝑐 is set at such coupling where the spectral weight of the ground state reaches 0.3 of the unrenormalized by EPI weight.
