Non-universal critical behaviour of a mixed-spin Ising model on the extended Kagome lattice

The mixed spin-1/2 and spin-3/2 Ising model on the extended Kagome lattice is solved by establishing a mapping correspondence with the eight-vertex model. When the parameter of uniaxial single-ion anisotropy
 tends to infinity, the model system becomes exactly solvable as the staggered eight...

description The mixed spin-1/2 and spin-3/2 Ising model on the extended Kagome lattice is solved by establishing a mapping correspondence with the eight-vertex model. When the parameter of uniaxial single-ion anisotropy
 tends to infinity, the model system becomes exactly solvable as the staggered eight-vertex model satisfying
 the free-fermion condition. The critical points within this manifold can be characterized by critical exponents
 from the standard Ising universality class. The critical points within another subspace of interaction parameters,
 which corresponds to a coexistence surface between two ordered phases, can be approximated by
 corresponding results of the uniform eight-vertex model satisfying the zero-field condition. This coexistence
 surface is bounded by a line of bicritical points that have non-universal continuously varying critical indices
