We study a Hamilton operator Ĥ for spin-1/2 with triple spin interactions. The eigenvalues and eigenvectors are determined and the unitary matrices exp (− iĤt/ℏ) are found. Entanglement of the eigenvectors is investigated. A Hamilton operator K̂ for spin-1 and triple spin interaction is also discussed.
Key words: Spin Interactions; Hamilton Operators; Entanglement.
