The principal Lee--Yang zeros of the Ising model need not decrease with the coupling

The Lee--Yang circle theorem states that, as a function of the external field h, the partition function of a ferromagnetic Ising model vanishes only on the imaginary axis $h=ix$. Consider a connected graph G on n vertices whose every edge carries the same coupling t≥0, the interaction divided by the temperature. For $t>0$, its partition function has K= n/2 zeros $x_1<
