Séminaire GPP : Samuel Belliard (U.Tours) : A derivation of the scalar product of XXZ spin chain with diagonal boundary conditions

Wednesday 15 May 2019, 14:30 → 17:00 Europe/Brussels

B203-05 (MdeHemptinne)

We will show how one can use the Drinfel’d second realization of the quantum group $U_q(\hat sl_2)$ to obtain a compact formula for the scalar product of off-shell Bethe vectors. The case of XXZ spin chain with diagonal boundary conditions will be considered as an example.
