Phys. Rev. Lett. 26, 303–304 (1971)Extension of the Lee-Yang Circle TheoremSee Also: Erratum Received 7 December 1970; published in the issue dated 8 February 1971 We study the zeros of the partition function of a classical spin system and compute a region of the complex fugacity plane where they necessarily lie. We recover the Lee-Yang circle theorem as a special example; we also find that a spin system with finite-range interaction has no phase transition at high temperature. © 1971 The American Physical Society URL:
