Phys. Rev. E 68, 031103 (2003) [9 pages]Quantum diffusion on a cyclic one-dimensional latticeReceived 28 March 2003; published 19 September 2003 The quantum diffusion of a particle in an initially localized state on a cyclic lattice with N sites is studied. Diffusion and reconstruction time are calculated. Strong differences are found for even or odd number of sites and the limit N⃗∞ is studied. The predictions of the model could be tested with microtechnology and nanotechnology devices. © 2003 The American Physical Society URL:
