@article{Delamotte2004NonperturbativeRA, title={Nonperturbative renormalization-group approach to frustrated magnets}, author={Bertrand Delamotte and D. Mouhanna and Matthieu Tissier}, journal={Physical Review B}, year={2004}, volume={69}, pages={134413} }

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 show that the unusual behaviors encountered in these systems, typically nonuniversal scaling, are hardly compatible with the hypothesis of a second order phase transition. Moreover, the fact that the scaling laws are significantly violated and that the anomalous dimension is negative in many cases…

Slow dynamics in glassy systems is often interpreted as due to thermally activated events between ‘metastable’ states. This emphasises the role of nonperturbative fluctuations, which is especially…

### Phase transitions in fully frustrated spin systems.

- PhysicsPhysical review. B, Condensed matter
- 1985

The phase structure and critical behavior of fully frustrated systems are studied, and a Landau-Ginzburg Hamiltonian is derived for the general case, assuming that both the (continuous) O(n) symmetry and some discrete symmetry are broken in the low-temperature phase.

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.

The renormalization group and the $\epsilon$-expansion are used to study the properties of the finite-temperature electroweak phase transition and it is found that the rate of baryon non-conservation after the transition is found to be larger than that given by the one-loop effective potential calculation.
