On critical behavior of phase transitions in certain antiferromagnets with complicated ordering
Andrei Mudrov, Konstantin Varnashev
Within the four-loop $\ve$ expansion, we study the critical behavior of certain antiferromagnets with complicated ordering. We show that an anisotropic stable fixed point governs t…
Critical thermodynamics of three-dimensional MN-component field model with cubic anisotropy from higher-loop εexpansion
Andrei Mudrov, Konstantin Varnashev
The critical thermodynamics of an -component field model with cubic anisotropy relevant to the phase transitions in certain crystals with complicated ordering is studied within…
Critical thermodynamics of three-dimensional MN-component field model with cubic anisotropy from higher-loop RG expansions
A. I. Mudrov, K. B. Varnashev
The critical behavior of an MN-component order parameter Ginzburg-Landau model with isotropic and cubic interactions describing antiferromagnetic and structural phase transitions i…
The stability of a cubic fixed point in three dimensions from the renormalization group
Konstantin Varnashev
The global structure of the renormalization-group flows of a model with isotropic and cubic interactions is studied using the massive field theory directly in three dimensions. The…
Stability of a cubic fixed point in three dimensions. Critical exponents for generic N
Konstantin Varnashev
The detailed analysis of the global structure of the renormalization-group (RG) flow diagram for a model with isotropic and cubic interactions is carried out in the framework of th…
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…
