Abstract
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 a nalogy between chaotic systems with dynamical localization and disorde red metals can indeed be exact. The role of symmetries is discussed.
