Surface critical behavior (SCB) refers to the singularities of physicalquantities on the surface at the bulk phase transition. It is closely relatedto and even richer than the bulk critical behavior. In this work, we show thatthree types of SCB universality are realized in the dimerized Heisenberg modelsat the (2+1)-dimensional O(3) quantum critical points by engineering thesurface configurations. The ordinary transition happens if the surface isgapped in the bulk disordered phase, while the gapless surface state generallyleads to the multicritical special transition, even though the latter isprecluded in classical phase transitions because the surface is in the lowercritical dimension. An extraordinary transition is induced by the ferrimagneticorder on the surface of the staggered Heisenberg model, in which the surfacecritical exponents violate the results of the scaling theory and thus seriouslychallenge our current understanding of extraordinary transitions.
