Effect of Single-Ion Anisotropy on Stability of Quantum and Thermal Entanglement in a Mixed-Spin Heisenberg Trimer

Hana Vargová, Jozef Strečka

The effect of uniaxial single-ion anisotropy on quantum entanglement is rigorously quantified using negativity in a mixed spin-( $1$ , $1/2$ , $1$ ) Heisenberg trimer, accounting for dif…

Robust global tripartite entanglement in a mixed spin-( $1$ , $1/2$ , $1$ ) Heisenberg trimer

Hana Vargová

We rigorously analyze the global tripartite entanglement in a Heisenberg trimer with mixed spins-( $1$ , $1/2$ , $1$ ) under varying exchange couplings between dissimilar and identical s…
