Fractional revivals of the quantum state in a tight-binding chain
Bing Chen, Z. Song, C. P. Sun · Physical Review A · 2007
We investigate the time evolution of a Gaussian wave packet (GWP) in a tight-binding chain with a uniform nearest-neighbor hopping integral. Analytical investigations and numerical simulations show that fractional revivals of the quantum state occur in this system, i.e., at appropriate times, a GWP can evolve into many copies of the initial state at different positions. The application of this quantum phenomenon to quantum information transfer in solid-state systems is discussed.
