 Election Citation

|
White is nominated for his invention and development of the numerical density-matrix- renormalization-group (DMRG) method, which has provided important new insights into models of strongly interacting fermions stretching across a range of systems in condensed matter physics, quantum chemistry and quantum information theory. |

Research Interests
|
|
Steven White's research is focused on the simulation of strongly correlated quantum systems, particularly in condensed matter physics and quantum chemistry. He and his group work both on developing new algorithms and on applying these methods to study strongly correlated systems. As a graduate student, White worked with Ken Wilson on applying numerical renormalization group ideas to quantum chemistry. As a postdoc, white developed quantum Monte Carlo methods to study the high temperature superconductors. As an assistant professor, White invented the density matrix renormalization group algorithm, and his work has revolved around DMRG since then.
White and collaborators have applied DMRG to study antiferromagnetism and superconductivy in one and two dimensional lattice systems. In simulations of the t-J and Hubbard models in two dimensions, they have demonstrated the existence of striped ground states, which appear in several of the high temperature superconductors. In simulations of the kagome Heisenberg model, they have demonstrated the existence of spin liquid ground states in simple and realistic models. White has developed extensions of DMRG to study dynamical and finite temperature properties, and to study the electronic structure of molecules in a quantum chemical basis.
