Electronic structure challenges for strongly correlated systems
I will give an overview of the challenges that modern electronic structure theory faces in describing strongly correlated chemical systems from molecules to materials. Our latest progress in combining density matrix renormalization group with pair-density functional theory as a new way to calculate correlation energy in multimetallic systems [1] will be discussed, together with the recent development of density matrix embedding methods based on multireference solvers for molecules [2] and materials [3].
