New approach to summation of field-theoretical series in models with strong coupling
A. I. Mudrov, K. B. Varnashev
A new approach to summation of divergent field-theoretical series is suggested. It is based on the Borel transformation combined with a conformal mapping and does not imply the kno…
New approach to Borel summation of divergent series and critical exponent estimates for an N-vector cubic model in three dimensions from five-loop εexpansions
Andrei Mudrov, Konstantin Varnashev
A new approach to summation of divergent field-theoretical series is suggested. It is based on the Borel transformation combined with a conformal mapping and does not imply the exa…
Critical behavior of three-dimensional magnets with complicated ordering from three-loop renormalization-group expansions
A. I. Sokolov, K. B. Varnashev
The critical behavior of a model describing phase transitions in 3D antiferromagnets with 2N-component real order parameters is studied within the renormalization-group (RG) approa…
Chiral transitions in three-dimensional magnets and higher order ε-expansion
S. A. Antonenko, A. I. Sokolov, K. B. Varnashev
The critical behaviour of helimagnets and stacked triangular antiferromagnets is analyzed in (4 - ε) dimensions within three-loop approximation. Numerical estimates for marginal va…
