Instability in the Potts model
Abstract
It is shown that for p>2 the transverse susceptibility of a p-dimensional Potts model with uniaxial order is negative, indicating that the ordered state is unstable, even though a stable critical fixed point is obtained for all p<103. © 1979 The American Physical Society.
