Abstract
An analytic form for the crossover of the conductivity tensor between
two Hall plateaux, as a function of the external magnetic field, is proposed.
The form of the crossover is obtained from the action of a symmetry
group, a particular subgroup of the modular group, on the upper-half
complex conductivity plane, by assuming that the β-function describing
the crossover is a holomorphic function of the conductivity. The group action
also leads to a selection rule, |p1q2−p2q1| = 1, for allowed transitions
between Hall plateaux with filling factors ѵ1 = p1/q1 and ѵ2 = p2/q2,
where q1 and q2 are odd.
