    Our theory shows that magneto-oscillation phases in biased graphene bilayers have anomalous behavior. Magneto-oscillations are only asymptotically periodic and, for low magnetic fields, reach the frequencies predicted quasiclassically. The frequencies are the same for K and K', but the quantum approach yields the valley-dependent gate-tunable phase corrections which give rise to two series of magneto-oscillations with the same frequency but shifted in phase.
