We develop a versatile first-principles many-body scheme for multiorbital lattice susceptibilities including full frequency-dependent local vertex effects and investigate the different instabilities in the metallic phase of the quasi-two-dimensional

We study the dynamics of charge-transfer insulators after photo-excitation using the three-band Emery model and a nonequilibrium extension of Hartree-Fock+EDMFT and GW+EDMFT. While the equilibrium properties are accurately reproduced by the Hartree-F

We study the dynamics of screening in photodoped Mott insulators with long-ranged interactions using a nonequilibrium implementation of the $GW$ plus extended dynamical mean-field theory formalism. Our study demonstrates that the complex interplay of

We discuss a parameter-free and computationally efficient ab initio simulation approach for moderately and strongly correlated materials, the multitier self-consistent $GW$+EDMFT method. This scheme treats different degrees of freedom, such as high-e

Sodium cobaltate NaxCoO2 as dopable strongly correlated layered material with a triangular sublattice still poses a challenging problem in condensed matter. The intriguing interplay between lattice, charge, spin, and orbital degrees of freedom leads
The cubic perovskite SrVO$_3$ is generally considered to be a prototype strongly correlated metal with a characteristic three-peak structure of the $d$-electron spectral function, featuring a renormalized quasiparticle band in between pronounced Hubb

The spin susceptibility of strongly correlated Sr$_2$RuO$_4$ is known to display a rich structure in reciprocal space, with a prominent peak at ${\bf Q}_i$=$(0.3,0.3,0)$. It is still debated if the resulting incommensurate spin-density-wave fluctuati

We shed light on the interplay between structure and many-body effects relevant for itinerant ferromagnetism in $\mathrm{La}\mathrm{Al}{\mathrm{O}}_{3}$/$\mathrm{Sr}\mathrm{Ti}{\mathrm{O}}_{3}$ heterostructures. The realistic correlated electronic st

The interface electronic structure of correlated LaTiO${}_{3}$/SrTiO${}_{3}$ superlattices is investigated by means of the charge self-consistent combination of the local density approximation (LDA) to density functional theory with dynamical mean-fi
