Topological Magnon Insulator in NonCoplanar Kagomé Antiferromagnets: Supplemental Material of arXiv:1608.04561
S. A. Owerre
Topological magnon insulators in insulating Kagomé ferromagnets have been extensively studied in a series of papers. It has been established that Dzyaloshinskii-Moriya interaction…
Topological Thermal Hall Effect in Frustrated Kagomé Antiferromagnets
S. A. Owerre
In frustrated magnets the Dzyaloshinsky-Moriya interaction arising from spin-orbit coupling can induce a magnetic long-range order. Here, we report a theoretical prediction of ther…
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…
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…
