Goldstone mode singularities in O(n) models

Monte Carlo (MC) analysis of the Goldstone mode singularities for the transverse and the longitudinal correlation functions, behaving as G⊥ (k) ≅ a k-λ⊥ and G|| (k) ≅ b k-λ|| in the ordered phase at k → 0, is performed in the three-dimensional O(n) models with n=2, 4, 10. Our aim is to test some cha...

Zusammenfassung:Monte Carlo (MC) analysis of the Goldstone mode singularities for the transverse and the longitudinal correlation functions, behaving as G⊥ (k) ≅ a k-λ⊥ and G|| (k) ≅ b k-λ|| in the ordered phase at k → 0, is performed in the three-dimensional O(n) models with n=2, 4, 10. Our aim is to test some challenging theoretical predictions, according to which the exponents λ⊥ and λ|| are non-trivial (3/2
