Quantum Entanglement in Nitrosyl Iron Complexes
S. M. Aldoshin, E. B. Feldman, M. A. Yurishchev
Recent magnetic susceptibility measurements for polycrystalline samples of binuclear nitrosyl iron complexes [Fe_2(C_3H_3N_2S)_2(NO)_4] (I) and [Fe_2(SC_3H_5N_2)_2(NO)_4] (II), sug…
Entanglement of systems of dipolar coupled nuclear spins at the adiabatic demagnetization
S. I. Doronin, E. B. Fel'dman, M. M. Kucherov +1
We consider the adiabatic demagnetization in the rotating reference frame (ADRF) of a system of dipolar coupled nuclear spins in the external magnetic field. The demagnetiz…
High-probability quantum state transfer among nodes of an open XXZ spin chain
E. B. Fel'dman, A. I. Zenchuk
This paper concerns the problem of the high probability state transfer among symmetrically placed nodes of the -nodes spins 1/2 chain with the Hamiltonian. We cons…
Evolution of spin entanglement and an entanglement witness in multiple-quantum NMR experiments
E. B. Fel'dman, A. N. Pyrkov
We investigate the evolution of entanglement in multiple-quantum (MQ) NMR experiments in crystals with pairs of close nuclear spins-1/2. The initial thermodynamic equilibrium state…
Multiple Quantum NMR Dynamics in Dipolar Ordered Spin Systems
S. I. Doronin, E. B. Fel'dman, E. I. Kuznetsova +2
We investigate analytically and numerically the Multiple Quantum (MQ) NMR dynamics in systems of nuclear spins 1/2 coupled by the dipole-dipole interactions in the case of the dipo…
Exact results on spin dynamics and multiple quantum dynamics in alternating spin-1/2 chains with XY-Hamiltonian at high temperatures
E. B. Fel'dman, M. G. Rudavets
We extend the picture of a transfer of nuclear spin-1/2 polarization along a homogeneous one-dimensional chain with the XY-Hamiltonian to the inhomogeneous chain with alternating n…
