Group Functions

Critical exponents of the O(m)-symmetric model are calculated in the case when dimension of space is noninteger. Calculations are performed in the frames of the field-theoretical approach using the three-loop approximation. Renormalization group functions in the Callan-Symanzik scheme are considered directly in noninteger dimensions. Perturbation theory expansions are resummed with the use of Padé-Borel transformation.

Good Agreement

Frustrated magnets are a notorious example where usual perturbative methods fail. Having recourse to an exact renormalization group approach, one gets a coherent picture of the physics of Heisenberg frustrated magnets everywhere between d=2 and d=4: all known perturbative results are recovered in a single framework, their apparent conflict is explained while the description of the phase transition in d=3 is found to be in good agreement with the experimental context.
