The quantum kicked rotor is investigated by field theoretical methods. It is shown that the effective theory describing the long wavelength physics of the system is precisely the supersymmetric nonlinear \(\sigma\) model for quasi-one-dimensional metallic wires. This proves that the analogy between chaotic systems with dynamical localization and disordered metals can indeed be exact. The role of symmetries is discussed. This note is taken from [1].

Certain conter examples are discussed in [2]. Also an example of the kicked Harper model shows that, even if in the classical limit this system is characterized by chaos and global diffusion, in the quantum case it may be diffusive, localized or ballistic (see [3] and Refs. therein). This shows that the validity of the field theoretical methods described in [1] requires certain additional conditions for their validity.
