摘要：

Recent results on the nature of the quantum critical point between Neel and valence bond solid (VBS) ordered phases of two-dimensional quantum magnets are examined by an attack from the VBS side. This approach leads to an appealingly simple physical description, and further insight into the properties of the transition.
