A quantum phase transition detected using pulsed fields. On one side of the transition (purple curve) the Hall resistivity grows steeply with field, once the linear regime has been accessed in high magnetic fields; on the other side (red curve), the increase is slower. Inset: the quantum phase transition is evidenced by the steep jump with increasing electron concentration in data from a dozen samples.
