- W4220778905 abstract "Entanglement of magnons in the nearest-neighbor Heisenberg model on Lieb lattice (LL) with out-of-plane Dzyaloshinskii–Moriya (DM) antisymmetric spin coupling and external magnetic field is studied. We obtain the behavior of the von Neumann entropy (VN) and concurrence as a function of the DM strength, analyzing the effect of magnon bands on quantum entanglement . Furthermore, the quantum correlations in some fermions models such as the two-dimensional non-Hermitian model (NH) on LL lattice and the tight-binding model (TB) on the LL lattice have been also analyzed. The effect of opening of the gap in the spectrum in these models generates an effect on the entanglement quantifiers as von Neumann entropy, concurrence and negativity. • Quantum entanglement on two-dimensional Lieb lattice is studied. • von Neumann entropy, concurrence and entanglement negativity are studied. • Influence of magnon bands on entanglement is investigated." @default.
