In the quantum kicked rotator it can be shown, that the plane wave | p ⟩ ⟩ with quantized momentum p = n ℏ ℏ play the role of the lattice sites states. The full mapping to the Anderson tight-binding model goes as follow (for a given eigenstates of the Floquet operator, with quasi-energy ω ω ) t n = − − ∫ ∫ − − π π π π d x 2 π π tan ⁡ ⁡ [ K cos ⁡ ⁡ ( x ) / 2 ] e − − i x n and ε ε n = tan ⁡ ⁡ ( ω ω / 2 − − n 2 / 4 ) Dynamical localization in the quantum kicked rotator then actually takes place in the momentum basis.
