Antiferromagnetic O(N) models in four dimensions
We study the antiferromagnetic O(N) model in the F4 lattice. Monte Carlo simulations are applied for investigating the behavior of the transition for N = 2, 3. The numerical results show a first order nature but with a large correlation length. The N → ∞ limit is also considered with analytical methods.
متن کاملMonte Carlo studies of antiferromagnetic spin models in three dimensions
The study of antiferromagnetic models (AFM) may give us some insights on the formulation of non trivial relativistic quantum field theories, as they present a very rich phase space and, presumably, new universality classes [1]. They are also interesting as related with models describing high temperature superconductors [2]; the two dimensional quantum Heisenberg antiferromagnet in the low tempe...
متن کاملA-models in three and four dimensions
We introduce and study a new 3d Topological Field Theory which can be associated to any compact real manifold X. This TFT is analogous to the 2d A-model and reduces to it upon compactification on an interval with suitable boundary conditions. It plays a role in 3d mirror symmetry as well as in the physical approach to the geometric Langlands duality. A similar TFT can be defined in four dimensi...

15 صفحه اولFinite-size effects on the chiral phase diagram of four-fermion models in four dimensions
We study the size dependence of the dynamical symmetry breaking in the fourdimensional Nambu-Jona-Lasinio model. We show that the presence of boundaries reduces the chiral breaking region, and this effect is strengthened for a larger number of compactified dimensions. A critical value for the length of the compactified dimensions exists, below which the dynamical symmetry breaking is not possib...
