The equivalence between the the ac-driven single-particle Krawtchouk Hamiltonian $\\hat{H}(t)$ and the non-interacting ac-driven bosonic junction Hamiltonian enables to determine in a closed form the quasi energy spectrum of $\\hat{H}(t)$ and the conditions for exact wave packet reconstruction (dynamic localization).
