Spin Glasses on Thin Graphs
In a recent paper [1] we found strong evidence from simulations that the Ising antiferromagnet on “thin” random graphs Feynman diagrams displayed a mean-field spin glass transition. The intrinsic interest of considering such random graphs is that they give mean field theory results without long range interactions or the drawbacks, arising from boundary problems, of the Bethe lattice. In this pa...
متن کاملSpin Glasses
The understanding of random magnetic systems known as spin glass has been one of the major challenges in condensed matter physics over that past two decades. Study of this state can be thought of as a rst step towards understanding more complex and disordered systems.This paper reviews some of the theoretical developmets in this eld and tries to answer the question how well are these systems un...

متن کاملGauge Theories, Spin Glasses and Real Glasses
In this talk I will show that usual spin glasses are a peculiar kind of Abelian gauge theory. I will shortly review the techniques used to study them. At the end I will consider more general models (e.g. spin glasses based on non Abelian gauge group) and I will discuss the relevance of these models to real glasses. Finally I will derive from first principles a generalised Vogel-Fulcher law for ...
متن کاملRecent numerical results on spin glasses
After giving an introduction to spin glasses, I will discuss recent numerical results on two topics which have been of interest in the field for many years: (i) whether there is a finite temperature phase transition in isotropic vector (e.g. Heisenberg) spin glasses, and (ii) whether there is a phase transition (called the AT line) in a spin glass in a magnetic field.
