We analyse the universal features of the critical behaviour of frustrated spin systems with noncollinear order. By means of the field theoretical renormalization group approach, we study the 3D model of a frustrated magnet and obtain pseudo-e expansions for its universal order parameter marginal dimensions. These dimensions govern accessibility of the renormalization group transformation fixed points, and, hence, define the scenario of the phase transition.

Pseudo-ε-expansion and the two-dimensional Ising model
The pseudo-ε-expansions for the coordinate of the fixed point g*, the critical exponents, and the sextic effective coupling constant g6 are determined for the two-dimensional Ising model on the basis
Critical behavior of O(2)⊗O(N) symmetric models
We investigate the controversial issue of the existence of universality classes describing critical phenomena in three-dimensional statistical systems characterized by a matrix order parameter with
Universality classes of the three-dimensional mn-vector model
We study the conditions under which the critical behaviour of the three-dimensional mn-vector model does not belong to the spherically symmetrical universality class. In the calculations, we rely on
Harmonic crossover exponents in O(n) models with the pseudo-epsilon expansion approach
We determine the crossover exponents associated with the traceless tensorial quadratic field and the third- and fourth-harmonic operators for $O(n)$ vector models by reanalyzing the existing six-loop
Critical behavior of two-dimensional cubic and MN models in the five-loop renormalization group approximation
The critical thermodynamics of the two-dimensional N-vector cubic and MN models is studied within the field-theoretical renormalization group (RG) approach. The {beta} functions and critical
Chiral spin pairing in helical magnets.
A concept of chiral spin pairing is introduced to describe a vector-chiral liquid-crystal order in frustrated spin systems and possible candidate materials are also discussed as new multiferroic systems.
Marginal dimensions of the Potts model with invisible states
We reconsider the mean-field Potts model with q interacting and r non-interacting (invisible) states. The model was recently introduced to explain discrepancies between theoretical predictions and
Critical exponents and the pseudo-є-expansion
We present the pseudo-є-expansions (τ-series) for the critical exponents of a λϕ4-type three-dimensional O(n)-symmetric model obtained on the basis of six-loop renormalization-group expansions. We


Critical behavior of frustrated spin models with noncollinear order
We study the critical behavior of frustrated spin models with noncollinear order, including stacked triangular antiferromagnets and helimagnets. For this purpose we compute the field-theoretic
XY frustrated systems: Continuous exponents in discontinuous phase transitions
XY frustrated magnets exhibit an unsual critical behavior: they display scaling laws accompanied by nonuniversal critical exponents and a negative anomalous dimension. This suggests that they undergo
Frustrated heisenberg magnets: A nonperturbative approach
A nonperturbative Wilson-like approach is used to get a coherent picture of the physics of frustrated Heisenberg magnets everywhere between d = 2 and d = 4 and recovers all known perturbative results in a single framework.
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
Nonperturbative renormalization-group approach to frustrated magnets
This article is devoted to the study of the critical properties of classical XY and Heisenberg frustrated magnets in three dimensions. We first analyze the experimental and numerical situations. We

We investigate models which have more than one coupling constant and which have no (codimension one) fixed point in the renormalization group flow in an e=4-d expansion. We show that the
Critical exponents of a three dimensional weakly diluted quenched Ising model
Universal and nonuniversal critical exponents of a three-dimensional Ising system with weak quenched disorder are discussed. Experimental, computational, and theoretical results are reviewed.
Phase transitions in anisotropic superconducting and magnetic systems with vector order parameters: Three-loop renormalization-group analysis.
The chiral fixed point of RG equations is found to exist and possess some domain of attraction provided N\ensuremath{\ge}4, and magnets with Heisenberg and XY-like spins should not demonstrate chiral critical behavior with unusual values of critical exponents; they can approach the chiral state only via first-order phase transitions.
Pseudo-ɛexpansion of six-loop renormalization-group functions of an anisotropic cubic model
Six-loop massive scheme renormalization group functions of a d=3-dimensional cubic model (J.M. Carmona, A. Pelissetto, and E. Vicari, Phys. Rev. B vol. 61, 15136 (2000)) are reconsidered by means of
