Colloquium: When Gutzwiller meets DMRG: a microscopic-wavefunction-guided approach to 2D correlated electrons

ABSTRACT

Two-dimensional (2D) strongly correlated electrons remain one of the central themes in modern physics. In this talk, we address a crucial issue: whether there exists a paradigm for studying 2D strongly correlated electrons by starting from their one-dimensional reduction. We will demonstrate that the newly proposed Gutzwiller-projected wavefunction-guided density matrix renormalization group (DMRG) is a promising method for this topic. This novel method will be illustrated through two examples: (1) Benchmarking the famous Kitaev honeycomb model; (2) Tackling a challenging problem -- determining the ground state of the antiferromagnetic Heisenberg model on a Kagome lattice.
