Kardar-Parisi-Zhang scaling in the Hubbard model
Cătălin Paşcu Moca, Miklós Antal Werner, Angelo Valli +2
We explore the Kardar-Parisi-Zhang (KPZ) scaling in the one-dimensional Hubbard model, which exhibits global symmetry at half-filling, for the pseudo-charg…
Strongly correlated physics in organic open-shell quantum systems
G. Gandus, A. Jayaraj, D. Passerone +3
Strongly correlated physics arises from electron-electron scattering within partially filled orbitals. Organic molecules in open-shell configurations are therefore good candidates…
Nematic spectral signatures of the Hund's metal
Laura Fanfarillo, Angelo Valli, Massimo Capone
We show, by means of dynamical mean-field theory calculations, that the experimental fingerprints of the nematic order in iron-based superconductors are intrinsically connected wit…
Designing a mechanically driven spin-crossover molecular switch via organic embedding
Sumanta Bhandary, Jan M. Tomczak, Angelo Valli
Among spin-crossover complexes, Fe-porphyrin (FeP) stands out for molecular spintronic applications: An intricate, yet favourable balance between ligand fields, charge transfer, an…
Boson-Exchange Parquet Solver for dual fermions
Friedrich Krien, Angelo Valli, Patrick Chalupa +3
We present and implement a parquet approximation within the dual-fermion formalism based on a partial bosonization of the dual vertex function which substantially reduces the compu…
Kondo screening in Co adatoms with full Coulomb interaction
Angelo Valli, Marc Philipp Bahlke, Alexander Kowalski +3
Using a numerically exact first-principles many-body approach, we revisit the "prototypical" Kondo case of a cobalt impurity on copper. Even though this is considered a well unders…
