    • A factor of 1/2 has been inserted into the right-hand side for the following reason: The orbit acquires a phase shift of -π/2 whenever it passes a caustic turning point. In this case, there are two caustics for a cyclotron orbit. Therefore there is an additional phase lag of -π that contributes to the nondynamical phase. van Houten's paper in Ref. [c12] has a nice discussion on the additional phase shift.

    • A similar formula for quantization of orbits in phase space has been derived by Wilkinson, in which it is not apparent that his Berry phase is related to the Hall conductivity. See

    • The scaling property of the Hofstadter spectrum guarantees that the semiclassical approximation, which is valid at the first order, remains valid at finer energy scales. See, for example
