The GW approximation in electronic structure theory has become a widespread tool for
predicting electronic excitations in chemical compounds and materials. In the realm of …

Quantum materials exhibit a wide array of exotic phenomena and practically useful
properties. A better understanding of these materials can provide deeper insights into …

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

Recent improvements in the control of quantum systems make it seem feasible to finally
build a quantum computer within a decade. While it has been shown that such a quantum …

We here present how a self-consistent solution of the dynamical mean-field theory equations
can be obtained using exact diagonalization of an Anderson impurity model with accuracies …

In the 0+ 1-dimensional imaginary-time path integral formulation of quantum impurity
problems, the retarded action encodes the hybridization of the impurity with the bath. In this …

We present a tensor network especially suited for multi-orbital Anderson impurity models
and as an impurity solver for multi-orbital dynamical mean-field theory (DMFT). The solver …

We present a solver for correlated impurity problems out of equilibrium based on a
combination of the so-called auxiliary master equation approach (AMEA) and the …

We implement and apply time-dependent density matrix renormalization group (TD-DMRG)
algorithms at zero and finite temperature to compute the linear absorption and fluorescence …

Quantitative simulation of electronic structure of solids requires treating local and nonlocal
electron correlations on an equal footing. We present a new ab initio formulation of Green's …
