Revivals in One-dimensional Quantum Walks with a Time and Spin-dependent Phase Shift
Muhammad Sajid, Qurat ul Ain, Hanifa Qureshi +1
We investigate the role of a time and spin-dependent phase shift on the evolution of one-dimensional discrete-time quantum walks. By employing Floquet engineering, a time and spin-…
