Cover Story: Cleaving highly oriented pyrolytic graphite with scotch tape produces nearly parallel line defects on the surface. Strain fluctuations, felt by electrons as effective gauge fields, localize and pair electrons on granules along the line defects, where they Bose condense, forming an emergent Josephson junction array in its bosonic topological insulator state. Cooper pairs tunnel without dissipation on the line defects, forming the edges of this topological insulator, when vortices are pinned by the extremely high conductivity of the graphene sheets, so that no quantum phase slips can occur. Electrons remain paired up to room temperature due to the tiny lateral dimension of the defects while vortices remain pinned up to room temperature due to their embedding in a 3D structure.

We revisit the interaction between a point charge and an inhomogeneous magnetic field that yields the magnetic quantum dot system. This magnetic field is defined by filling the whole space, except for a region of radius r0. Then, we assume that there...
