[25] However, not all the possible combinations of these values ofh and ¯h are realized as local primary operators in the CFT. The Ising CFT only includes the three “diagonal” primary operators that haveh=h.

Witryna24 cze 2016 · In his paper, Kitaev essentially discusses three different ways of seeing that this has edge states described by the Ising CFT. Let me list them in order of ascending sophistication: Through a direct calculation in appendix B, he shows that the edge is described by a fermionic band that crosses the zero-energy line once.

WitrynaJ'ai simulé quelques modèles d'Ising 2d à température critique sur un réseau triangulaire et j'essaie maintenant de vérifier que les fonctions de corrélation sont correctes. Je l'ai déjà fait pour l'opérateur de spin ( σ σ ) et j'aimerais faire la même chose pour l'opérateur local d'énergie qui devrait satisfaire la dépendance ... Witryna8. I would say that while the Ising CFT is a CFT of the usual sort, the Majorana CFT is a more refined object which can be examined in any spin structure on the spacetime …
