We study the complex-temperature properties of a rare example of a statistical mechanical model which is exactly solvable in an external symmetry-breaking field, namely, the Ising model on the square lattice with βH = ±iπ/2. This model... more
We study the complex-temperature properties of a rare example of a statistical mechanical model which is exactly solvable in an external symmetry-breaking field, namely, the Ising model on the square lattice with βH = ±iπ/2. This model was solved by Lee and Yang (1). We first determine the complex-temperature phases and their boundaries. From a low-temperature, high-field series expansion of
