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 …

Recent experiments on geometrically frustrated kagome metal A V3Sb5 (A= K, Rb, Cs) have
revealed the emergence of the charge loop current (cLC) order near the bond order (BO) …

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

One novel arena for designing superconductors with high TC is the flat band system. A basic
idea is that flat bands, arising from quantum mechanical interference, give unique …

We review nonperturbative numerical calculations on dynamical properties of the two-
dimensional Hubbard model and their relevance to various spectroscopic experiments on …

We analyze the highly nonperturbative regime surrounding the Mott-Hubbard metal-to-
insulator transition (MIT) by means of dynamical mean field theory (DMFT) calculations at …

In this work, we analyze in detail the occurrence of divergences in the irreducible vertex
functions for one of the fundamental models of many-body physics: the Anderson impurity …

The self-energy embedding theory (SEET), in which the active space self-energy is
embedded in the self-energy obtained from a perturbative method treating the non-local …

We present a formalism for strongly correlated systems with fermions coupled to bosonic
modes. We construct the three-particle irreducible functional K by successive Legendre …

Diagrammatic extensions of dynamical mean-field theory (DMFT) such as the dynamical
vertex approximation (D Γ A) allow us to include nonlocal correlations beyond DMFT on all …
