Lazy Open Quantum Walks
Garreth Kemp, Ilya Sinayskiy, Francesco Petruccione
Open quantum walks (OQWs) describe a quantum walker on an underlying graph whose dynamics is purely driven by dissipation and decoherence. Mathematically, they are formulated as co…

Pauli Lubanski Vector Operator, Eigenvalue Problem and Entanglement
Garreth Kemp, Willi-Hans Steeb
We study an eigenvalue problem for a spin matrix arising in the Pauli Lubanski vector operator. Entanglement of the eigenvectors and its connection with degeneracy is discussed.
