David Campbell

David Campbell is a Professor of Physics, Electrical and Computer Engineering, and Materials Science at Boston university. His research covers three distinct but overlapping areas. With his students and other collaborators, he is investigating graphene and other two-dimensional electronic membranes. He has also extended this research to other two-dimensional materials, and in particular to several studies of phosphorene (two-dimensional black phosphorus) and the semiconducting transition metal dichalcogenide MoS2, which has a direct bandgap on the order of 1-2 eV in monolayer form. His long-term interest in “intrinsic localized modes” (ILMs). This has led him to study the possible existence of ILMs in Bose-Einstein Condensates (BECs) trapped in optical lattices, so that the effects of discreteness (from the optical lattice) and nonlinearity (from the BEC) were both present. In addition, he has been working with several different collaborators with the Functional Renormalization Group (FRG), and applying it to a wide range of models for novel, strongly correlated electronic systems.
