▎ 摘  要

We propose that bilayer graphene can provide an experimental realization of deconfined criticality. Current experiments indicate the presence of Neel order in the presence of a moderate magnetic field. The Neel order can be destabilized by application of a transverse electric field. The resulting electric field induced state is likely to have valence bond solid order, and the transition can acquire the emergent fractionalized and gauge excitations of deconfined criticality.
