FIG. 1.

Energy states with angular momentum index as a function of the square root of the kink/antikink potential height (lower inset) for a bilayer graphene ring as schematically shown in the upper inset, considering a ring radius . Full (empty) symbols refer to negative (positive) . The black solid lines depicts the limits between the confined states and the continuum, whereas the thin dotted line is .

FIG. 2.

Energy spectrum for as a function of the ring radius for bilayer graphene in the presence of a circular kink/antikink potential of height . Full (empty) symbols refer to negative (positive) values of . Three lines are drawn to help visualization: the black solid lines delimits the potential height , whereas the thin dotted line is .
