Coherence, Transport, and Chaos in 1D Bose-Hubbard Model: Disorder vs. Stark Potential
Asad Ali, M. I. Hussain, Saif Al-Kuwari +6
Quantum coherence and phase transitions are studied in a finite one-dimensional Bose--Hubbard model using exact diagonalization under thermal fluctuations, a Stark potential, and d…
Fingerprints of cluster-based Haldane and bound-magnon states in a spin-1 Heisenberg diamond chain
Azam Zoshki, Hamid Arian Zad, Katarina Karlova +1
We investigate magnetic and thermodynamic properties of a spin-1 Heisenberg diamond chain in a magnetic field using a combination of analytical and numerical methods including the…
Quantum Entanglement Generation in the Heterometallic NiGd Complexes
Hamid Arian Zad, Michal JaÅ¡Äur, Azam Zoshki +2
We investigate various types of quantum entanglement in the octanuclear heterometallic complexes denoted as NiGd under an external magnetic field, using t…
Jahn-Teller Effect for Controlling Quantum Correlations in Hexanuclear Fe Magnets
Hamid Arian Zad, Michal JaÅ¡Äur, Asad Ali +2
We investigate the low-temperature magnetic and quantum properties of hexanuclear Fe complexes under an external magnetic field. We primarily study the impact of competin…
Multipartite Entanglement and Quantum Sensing in a Spin-5/2 Heisenberg Molecular Iron(III) Triangle
Hamid Arian Zad, Jozef StreÄka, Winfried Plass
This study provides insights into the static and dynamic quantum properties of the trinuclear high-spin iron(III) molecular complex $[\mathrm{Fe}_3\mathrm{Cl}_3(\mathrm{saltag^\mat…
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…
