Intertwined Superconductivity and Magnetism from Repulsive Interactions in Kondo Bilayers
Clara S. Weber, Dominik Kiese, Dante M. Kennes +1
While superconductors are conventionally established by attractive interactions, higher-temperature mechanisms for emergent electronic pairing from strong repulsive electron-electr…

Embedded multi-boson exchange: A step beyond quantum cluster theories
Dominik Kiese, Nils Wentzell, Igor Krivenko +3
We introduce a diagrammatic multi-scale approach to the Hubbard model based on the interaction-irreducible (multi-boson) vertex of a small cluster embedded in a self-consistent med…

Machine learning-based compression of quantum many body physics: PCA and autoencoder representation of the vertex function
Jiawei Zang, Matija Medvidović, Dominik Kiese +3
Characterizing complex many-body phases of matter has been a central question in quantum physics for decades. Numerical methods built around approximations of the renormalization g…
