Phys. Rev. B 24, 2878–2880 (1981)Field-theoretical approach to multicritical behavior near free surfaces
The critical behavior of a semi-infinite n-vector model in 4-ε dimensions near the special transition is studied. The renormalization of the relevant surface operators is discussed and explicitly carried out in two-loop order. It is found that the crossover exponent φs related to the square of the order parameter in the surface does not satisfy the relation φs=1-ν due to Bray and Moore. © 1981 The American Physical Society URL:
