Critical exponents for the two dimensional spin 12 XY model from a seven spin cell real space renormalization group calculation

In this paper we report on a real space renormalization group calculation for the spin 12 XY model on a triangular lattice using cells of seven spins. We applied a linear transformation and imposed a marginality criterion to find η = 0.26 and v = 2.28. The value of η agrees with the value obtained by Kosterlitz for the planar rotator model (η = 0.25).
