The quantum dynamics of two coupled large spins    [PDF]

V. E. Zobov

We calculate the time evolution of mean spin components and the squared I-concurrence of two coupled large spins S. As the initial conditions we take two cases: spin coherent states and uniform superposition states. For the spin coherent states we have obtained the asymptotic for-mulas at S>>1 and t<View original: http://arxiv.org/abs/1211.4926
