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 …

Quantum impurity models describe an atom or molecule embedded in a host material with
which it can exchange electrons. They are basic to nanoscience as representations of …

The Hubbard model represents the fundamental model for interacting quantum systems and
electronic correlations. Using the two-dimensional half-filled Hubbard model at weak …

Studies of the electromagnetic response of various classes of correlated electron materials
including transition-metal oxides, organic and molecular conductors, intermetallic …

We introduce density matrix embedding theory (DMET), a quantum embedding theory for
computing frequency-independent quantities, such as ground-state properties, of infinite …

The insulator–metal transition remains among the most studied phenomena in correlated
electron physics. However, the spontaneous formation of spatial patterns amidst insulator …

Electron correlation and spin frustration are among the central issues in condensed matter
physics, and their interplay is expected to bring about exotic phases with both charge and …

We present a comprehensive dynamical mean field study of the triangular lattice moiré
Hubbard model, which is believed to represent the physics of moiré bilayer transition metal …

A first-principles density-functional description of the electronic structures of the high-T c
cuprates has remained a long-standing problem since their discovery in 1986, with …

We show how an accurate first-principles treatment of the antiferromagnetic ground state of
La 2 CuO 4 can be obtained without invoking any free parameters such as the Hubbard U …
