Noncollinear Antiferromagnetic Haldane Magnon Insulator
S. A. Owerre
In this Letter we present a comprehensive study of topological magnon bands and thermal Hall effect in non-collinear antiferromagnetic systems on the honeycomb lattice with an intr…
Topological Magnon Bands in Ferromagnetic Star Lattice
S. A. Owerre
The experimental observation of topological magnon bands and thermal Hall effect in a kagomé lattice ferromagnet Cu(1-3, bdc) has inspired the search for topological magnon effects…
Antiferromagnetic molecular nanomagnets with odd-numbered coupled spins
S. A. Owerre, J. Nsofini
In recent years, studies on cyclic molecular nanomagnets have captivated the attention of researchers. These magnets are finite in size and contain very large spins. They are inter…
A toy model for quantum spin Hall effect
S. A. Owerre, J. Nsofini
In this Communication, we investigate a toy model of three-dimensional topological insulator surface, coupled homogeneously to a fictitious pseudo spin- particle. We s…
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…
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…
