Query: Periodic Electronic Structure Calculations With Density Matrix Embedding
  Theory   We extend density matrix embedding theory to periodic systems, resulting in
an electronic band structure method for solid-state materials. The electron
correlation can be captured by means of a local impurity model using various
choices of wave function methods. The method is able to describe not only the
ground-state energy but also the quasiparticle band picture via the
real-momentum space implementation. We investigate the performance of periodic
DMET in describing the ground-state energy as well as the electronic band
structure for one-dimensional solids. Our results show that DMET are in good
agreement with other many-body techniques at a cheaper computational cost. We
anticipate that the periodic DMET can be a promising first principle method for
strongly correlated materials.
