| dc.description.abstract | In this thesis, we find that the quantum mechanical treatment of the magnonic Klein paradox reproduces classical spin current enhancement. In addition, it follows that in a vacuum we get spontaneous magnon emission. This emission is interesting for quantum entanglement and a potential Hawking radiation analog. | |

| dc.subject | We show how the quantum mechanical treatment of magnon-antimagnon coupling leads to the enhancement of magnonic spin current analogous to the bosonic Klein paradox. In addition to this we investigate the scattering dynamics of this magnonic system resulting in a description of spontaneous magnon emission in an in-state vacuum. The spontaneous emission will then be compared to thermal emission to get a critical temperature which entails measureability | |
