Artificial multibarrier

Most theoretical treatments of decay consider the time evolution of an initial state tunneling out of single well [81-85]. However, the present-day possibility of designing the potential parameters of artificial quantum systems [61, 86], opens the way to study the issue of decay in more complex potential profiles as exemplified by semiconductor multibarrier systems of finite length which are formed by a succession of alternating barriers and wells [57] and other artificial multibarrier structures as ultracold atomic gases in optical lattices [86]. 

Our results are of a general validity in quantum mechanics and hence one may consider other artificial multibarrier structures as, for example, ultracold atomic gases in optical lattices [86] and in optical tests of quantum mechanics [96].
