The dynamical behavior of a star network of spins, wherein each N decoupled spin interacts with a central spin through non-uniform Heisenberg XX interaction, is exactly studied. The time-dependent Schrödinger equation of the spin system model is solved starting from an arbitrary initial state. The resulting solution is analyzed and briefly discussed. © 2009 The Royal Swedish Academy of Sciences.
