Z. Gulacsi et al., HIDDEN ORDERING EFFECTS IN D=1 DIMENSIONAL ISING-MODEL WITH MIRROR-IMAGE TYPE INTERACTIONS, Czechoslovak journal of Physics, 46, 1996, pp. 1911-1912
An Ising chain with mirror-image type interactions was analyzed exactl
y at nonzero temperatures. However the thermodynamic function of the m
odel is analytic, a careful study revealed an accentuately rich intern
al physics whose interpretation in terms of correlation functions lead
us to consider hidden internal ordering within the system at least of
short-range type.
