Quantum discord for two-qubit CS states: Analytical solution
M. A. Yurishchev
We found an universal local unitary (orthogonal) transformation which transforms any centrosymmetric (CS) density matrix ρ_{CS} into the X density matrix ρ_X: H\otimes Hρ_{CS}H\oti…
Quantum correlations in a system of nuclear s=1/2 spins in a strong magnetic field
E. B. Fel'dman, E. I. Kuznetsova, M. A. Yurishchev
Entanglement and quantum discord for a pair of nuclear spins in a nanopore filled with a gas of spin-carrying molecules (atoms) are studied. The correlation functions descr…
Fluctuations of Quantum Entanglement
E. B. Fel'dman, M. A. Yurishchev
It is emphasized that quantum entanglement determined in terms of the von Neumann entropy operator is a stochastic quantity and, therefore, can fluctuate. The rms fluctuations of t…
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…
Magnetic susceptibility of quasi-one-dimensional Ising superantiferromagnets FeTAC and MCl_2*2NC_5H_5 (M=Co, Fe): Approximations with L x oo and L x L x oo chain clusters
M. A. Yurishchev
The temperature dependence of the zero-field susceptibilities of 2D and 3D Ising lattices with anisotropic coupling is analyzed. Infinite 2D and 3D lattices are approximated, respe…
Critical temperature of a fully anisotropic three-dimensional Ising model
M. A. Yurishchev
The critical temperature of a three-dimensional Ising model on a simple cubic lattice with different coupling strengths along all three spatial directions is calculated via the tra…
