โœฆ Synopsis

Special features

of the complex temperature zeros of the partition function of the two-dimensional Ising model on completely anisotropic triangular lattices with all "odd" interactions, such as one with interaction ratios 5 : 3 : 1, are investigated. A bifurcation of one of the boundary lines at the imaginary axis occurs. An analytical explanation of this bifurcation is provided, and the algebraic reduction of the bifurcation eliminant to a symmetrical form is reported. Also, the end-points of lines of pure imaginary zeros are related to the critical point and disorder point equations.

The partition function of the two-dimensional lattice HP model for protein folding is computed by exact enumeration. For a protein-like sequence, the distribution of partiton function zeros shows roughly a two-ring pattern, while for a nonprotein-like sequence, the outer ring of zeros is ill-develop
