Abstract: Using the semi-classical approximation we calculate the quantum fluctuations of the two‐dimensional electronic scattering cross‐section from three hard disks in a magnetic field. The three‐disk billiard is a schematic model for a three‐lead mesoscopic (ballistic) junction. As the magnetic field increases the classical trajectories in the three‐disk billiard undergo a hyperbolic–non‐hyperbolic transition, i.e. a transition from a completely chaotic phase space to a phase space with stable islands. We show that the traces of this transition can be seen in the quantum fluctuations of the cross‐section and should therefore influence the resistance fluctuations of ballistic junctions.
