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…

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

Hana VargovÃ¡, Jozef StreÄka

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…

The quantification of a genuine tetrapartite entanglement in a mixed spin-(1/2,1) Heisenberg tetramer

Hana VargovÃ¡, Jozef StreÄka

The genuine tetrapartite entanglement of a mixed spin-(1/2,1) Heisenberg tetramer is quantified according to the three different approaches incorporated all seven global bisections…

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

Hana VargovÃ¡

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…
