We use the topological heavy fermion (THF) model and its Kondo lattice (KL) formulation to study the possibility of a symmetric Kondo (SK) state in twisted bilayer graphene. Via a large …
We explore the interplay of electron-electron correlations and spin-orbit coupling in the model Fermi liquid Sr 2 RuO 4 using laser-based angle-resolved photoemission …
We describe the hybridization-expansion continuous-time quantum Monte Carlo code package “w2dynamics”, developed in Wien and Würzburg. We discuss the main features of …
The demonstration of superconductivity in nickelate analogs of high T c cuprates provides new perspectives on the physics of correlated electron materials. The degree to which the …

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 study the temperature evolution of quasiparticles in the correlated metal Sr 2 RuO 4. Our angle resolved photoemission data show that quasiparticles persist up to temperatures …
The interplay of dynamical correlations and electronic ordering is pivotal in shaping phase diagrams of correlated quantum materials. In magic-angle twisted bilayer graphene …
The crossover from fluctuating atomic constituents to a collective state as one lowers temperature or energy is at the heart of the dynamical mean-field theory description of the …
We study the many-body electronic structure of the stoichiometric and electron-doped trilayer nickelate Pr 4 Ni 3 O 8 in comparison to that of the stoichiometric and hole-doped …
