Description: 
Following the Bethe ansazt procedure the exact dynamics of an XX central spin model is revealed. Particular initial conditions are analyzed and the consequent time evolution is compared with the exact solution obtained by solving the time-dependent Schrüdinger equation. The interest towards spin systems and in particular central spin systems, is motivated by the recent developments in more applicative contexts.
