Matrice de densité d’intrication à partir de la base fermionique

Fedor Smirnov (LPTHE)

In this talk I shall explain how the exact density matrix for integrable spin chain can be constructed using the fermionic basis. I shall emphasise the similarity of the construction with the Operator Product Expansion of the QFT. XXX spin chain will be considered as an example.
