▎ 摘  要

We discuss the spectrum of a magnetic quantum dot in graphene. Such a dot can be formed by an inhomogeneous magnetic (or strain-induced pseudo-magnetic) field. We present detailed calculations for a circularly symmetric dot, where the magnetic field is constant except within a disk where it vanishes. The number of bound states in the dot is determined by the missing flux through the disk.
