Entanglement entropy and quantum field theory: a non-technical introduction
Pasquale Calabrese, John Cardy
In these proceedings we give a pedagogical and non-technical introduction to the Quantum Field Theory approach to entanglement entropy. Particular attention is devoted to the one s…
The critical behavior of magnetic systems described by Landau-Ginzburg-Wilson field theories
Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari
We discuss the critical behavior of several three-dimensional magnetic systems, such as pure and randomly dilute (anti)ferromagnets and stacked triangular antiferromagnets. We also…
Critical behavior of vector models with cubic symmetry
P. Calabrese, A. Pelissetto, E. Vicari
We report on some results concerning the effects of cubic anisotropy and quenched uncorrelated impurities on multicomponent spin models. The analysis of the six-loop three-dimensio…
Comment on ``Bicritical and Tetracritical Phenomena and Scaling Properties of the SO(5) Theory,'' [X. Hu, Phys. Rev. Lett. 87, 057004 (2001)]
Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari
We show that, in the most general -component theory with symmetry O(n_1)+O(n_2), N=n_1+n_2\geq 3, the O(N)-symmetric fixed point has (at least) three unstable directions: the te…
