Matrice de densité d’intrication à partir de la base fermionique. – (Fedor Smirnovi / LPT / Seminar). – 25/03/2025, 14H
25 mars; 14h00 - 15h00
Séminaire LPT
Fedor Smirnov (LPTHE)
Seminar LPT, 25/03/2025, 14H, 3R4, salle de conférence
Summary :
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.
