Entanglement-entropy analysis of critical and topological quantum phases in a frustrated spin-1/2 Heisenberg ladder

Azadeh Ghannadan, Hana VargovÃ¡, 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 $I^\pm$ . Thi…

Molecular Nanomagnet $Cu^{II} Ni^{II} Cu^{II}$ 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…
