Professor White studies strongly correlated quantum systems using numerical simulations. These systems include high temperature superconductors and exotic magnetic systems, including spin liquids. Professor White utilizes tensor network methods, including the first and most successful such method, the density matrix renormalization group (DMRG), which White invented in 1992. The field of tensor networks has grown enormously in the last decade, with applications to many areas of physics and to other fields, such as quantum chemistry.
