Théorie conforme des champs

Une théorie conforme des champs ou théorie conforme (en anglais, conformal field theory ou CFT) est une variété particulière de théorie quantique des champs admettant le groupe conforme (en) comme groupe de symétrie. Ce type de théorie est particulièrement étudié lorsque l'espace-temps y est bi-dimensionnel car en ce cas le groupe conforme est de dimension infinie et bien souvent la théorie est alors exactement soluble. Ces théories sont utiles pour décrire certains systèmes physiques réels se comportant effectivement comme des systèmes bidimensionnels, mais également dans des domaines plus théoriques telle la théorie des cordes où la quantification du modèle sigma non linéaire vivant sur la surface d'univers d'une corde est une théorie conforme.

Facade of the reassembled Temple of Derr The Temple of Derr or el-Derr is a speos or rock-cut Egyptian temple, now located in New Amada in Lower Nubia. It was built during the 19th dynasty by Pharaoh Ramesses II.[1] It is the only rock-cut temple in Nubia, which was constructed by this pharaoh on the right (or east) bank of the Nile and used to stand at el-Derr.[2] The temple's unique position was probably because the river on its approach to the Korosko bend flows in an 'unnatur…
