Katsura-Nagaosa-Balatsky magnetoelectricity in molecular magnets: Bipartite entanglement transfer by means of rotating electric field
Zhirayr Adamyan, Ani Chobanyan, Vadim Ohanyan +4
We investigate quantum entanglement in a spin-1/2 Heisenberg trimer with spin-induced electric polarization described by the Katsura-Nagaosa-Balatsky (KNB) mechanism in the presenc…

Entanglement-entropy analysis of critical and topological quantum phases in a frustrated spin-1/2 Heisenberg ladder
Azadeh Ghannadan, Hana Vargová, Jozef Genzor +2
We investigate the ground-state phase diagram of a frustrated spin-1/2 Heisenberg ladder in the transverse magnetic field with an anisotropic inter-rung exchange coupling . Thi…

Molecular Nanomagnet as Resource for Bipartite and Tripartite Quantum Entanglement and Coherence
Azadeh Ghannadan, Hamid Arian Zad, Saeed Haddadi +3
We investigate key quantum characteristics of the mixed spin-(1/2,1,1/2) Heisenberg trimer under the influence of an external magnetic field. Specifically, we analyze the distribut…
