Computational quantum many-body theory

@ Seoul National University


We develop numerical methods for studying quantum many-body problems and apply them to investigate various systems, such as

  • strongly correlated electrons;

  • mesoscopic and nanoscale quantum devices; and

  • ultracold atoms in optical lattices.

We focus on two families of quantum many-body methods, namely

  • tensor network methods, including numerical renormalization group (NRG), density matrix renormalization group (DMRG), and projected entangled pair states (PEPS); and

  • dynamical mean-field theory (DMFT) and its nonlocal extensions.
