Location of the Zeros of the Grand Partition Function of Certain Classes of Lattice Gases
It is proved that there exist lattices in any dimension such that the grand partition function of the corresponding repulsive lattice gas has all the zeros in the fugacity on the negative real axis. The argument also furnishes a new proof of the Lee‐Yang circle theorem.
