Quantum steering has attracted great interest in the last decade,especially in the celebrated optomechanical,cold atom,and quantum optical systems.However,there is still a lack of studies on quantum steering in circui...

In this paper, we present a comprehensive investigation of the effects of the transverse correlation function (TCF) on the thermodynamic properties of Heisenberg antiferromagnetic (AFM) and ferromagnetic (FM) sy...

The thermal quantum discord (QD) is studied in a two-qubit Heisenberg XXZ system with DzyaloshinskiiMoriya (DM) interaction. We compare the thermal QD with thermal entanglement in this system and find remarkable d...

We construct the integrable deformations of the Heisenberg supermagnet model with the quadratic constraints (i) S2=3S - 2I, for S ∈ USPL(2/1)/S(U(2)×U(1)) and (ii) S2=S, for S ∈ USPL(2/1)/S(L(1/1)...

Multiferroic behavior in an isotropic Heisenberg spin glass with Gaussian random fields, incorporated by magneto-electric coupling derived from the Landau symmetry argument, are investigated. Electric dipole glass tra...

Quantum teleportation via the entangled channel composed of a two-qubit Heisenberg XYZ model with Dzyaloshinski-Moriya (DM) interaction in the presence of intrinsic decoherence has been investigated. We find that th...

In this paper, we consider the global existence of one-dimensional nonautonomous (inhomogeneous) Schrodinger flow. By exploiting geometric symmetries, we prove that, given a smooth initial map, the Cauchy problem of t...

In this paper we show that there exists a unique local smooth solution for the Cauchy problem of the Schrodinger flow for maps from a compact Riemannian manifold into a complete Kahler manifold, or from a Euclidean sp...
