Theoretical Studies of Dimeric Exchange-Coupled Single-Molecule Magnets
S. A. Owerre
We study a molecular dimer model that takes higher order interaction term as well as antisymmetric term into account. We mainly focus on the theoretical quantum properties that are…
Haldane-like antiferromagnetic spin chain in the large anisotropy limit
S. A. Owerre, M. B. Paranjape
We consider the one dimensional, periodic spin chain with sites, similar to the one studied by Haldane \cite{hal}, however in the opposite limit of very large anisotropy and sm…
Quantum-classical transition of the escape rate of a biaxial ferromagnetic spin with an external magnetic field
S. A. Owerre, M. B. Paranjape
We study the model of a biaxial single ferromagnetic spin Hamiltonian with an external magnetic field applied along the medium axis. The phase transition of the escape rate is inve…
Macroscopic quantum tunneling and quantum-classical phase transitions of the escape rate in large spin systems
S. A. Owerre, M. B. Paranjape
This article presents a review on the theoretical and the experimental developments on macroscopic quantum tunneling and phase transition of the escape rate in spin systems. We pre…
Rotating Entangled States of an Exchange-Coupled Dimer of Single-Molecule Magnets
S. A. Owerre
An antiferromagnetically exchange-coupled dimer of single molecule magnets which possesses a large spin tunneling has been investigated. For this system the ground and first excite…
