Strong electronic correlations pose one of the biggest challenges to solid state theory.
Recently developed methods that address this problem by starting with the local, eminently …

Numerical results for ground-state and excited-state properties (energies, double
occupancies, and Matsubara-axis self-energies) of the single-orbital Hubbard model on a …

The correlation functions of quantum systems—central objects in quantum field theories—
are defined in high-dimensional space-time domains. Their numerical treatment thus suffers …

We review recent developments in electronic structure calculations that go beyond state-of-
the-art methods such as density functional theory (DFT) and dynamical mean field theory …

We compute the ground-state phase diagram of the Hubbard and frustrated Hubbard
models on the square lattice with density matrix embedding theory using clusters of up to 16 …

Motivated by cuprate and nickelate superconductors, we perform a comprehensive study of
the superconducting instability in the single-band Hubbard model. We calculate the …

The discovery of different phases as a result of correlations, especially in low-dimensional
materials, has been always an exciting and fundamental subject of research. Recent …

We study the competition between stripe states with different periods and a uniform d-wave
superconducting state in the extended two-dimensional Hubbard model at 1/8 hole do** …

We study competitions among charge-uniform and-inhomogeneous states in two-
dimensional Hubbard models by using a variational Monte Carlo method. At realistic …

We derive ab initio low-energy effective Hamiltonians (LEH) for high-temperature
superconducting (SC) copper oxides Bi 2 Sr 2 CuO 6 (Bi2201, N ℓ= 1, T c exp∼ 10 K), Bi 2 …
