Abstract

We study a Fermi Hamilton operator $$\hat{K}$$ K ^ which does not commute with the number operator $$\hat{N}$$ N ^ . The eigenvalue problem and the Schrödinger equation are solved. Entanglement is also discussed. Furthermore, the Lie algebra generated by the two terms of the Hamilton operator is derived, and the Lie algebra generated by the Hamilton operator and the number operator is also classified.
