Entanglement dynamics of spin systems in pure states Academic Article uri icon

abstract

  • Abstract We investigate numerically the appearance and evolution of entanglement in spin systems prepared initially in a pure state. We consider the dipolar coupling spin systems of different molecular structures: benzene C 6 H 6, cyclopentane C 5 H 10, sodium butyrate CH 3 (CH 2) 2 CO 2 Na, and calcium hydroxyapatite Ca 5 (OH)(PO 4) 3. Numerical simulations show that the close relationship exists between the intensity of second order (2Q) coherences and concurrences of nearest spins in a cyclopentane molecule.
