Phys. Rev. Lett. 77, 4536–4539 (1996)Field Theory of the Quantum Kicked RotorReceived 20 June 1996; published in the issue dated 25 November 1996 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 σ 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. © 1996 The American Physical Society URL:
