Liouvillian interpolation of the self-energy of cluster dynamical mean-field theories
Mathias Pelz, Jan von Delft, Andreas Gleis
Two widely-used non-local extensions of dynamical mean-field theory (DMFT), namely cellular DMFT (CDMFT) and the dynamical cluster approximation (DCA), both yield self-energies mar…
Connecting single-layer - to Kondo lattice models: Exploration with cold atoms
Hannah Lange, Eugene Demler, Jan von Delft +2
The Kondo effect, a hallmark of many-body physics, emerges from the antiferromagnetic coupling between localized spins and conduction fermions, leading to a correlated many-body si…
Interpretable Artificial Intelligence (AI) Analysis of Strongly Correlated Electrons
Changkai Zhang, Jan von Delft
Artificial Intelligence (AI) has become an exceptionally powerful tool for analyzing scientific data. In particular, attention-based architectures have demonstrated a remarkable ca…
Tangent space Krylov computation of real-frequency spectral functions: Influence of density-assisted hopping on 2D Mott physics
Oleksandra Kovalska, Jan von Delft, Andreas Gleis
We present a tangent-space Krylov (TaSK) method for efficient computation of zero-temperature real-frequency spectral functions on top of ground state (GS) matrix product states (M…
Testing the parquet equations and the U(1) Ward identity for real-frequency correlation functions from the multipoint numerical renormalization group
Nepomuk Ritz, Anxiang Ge, Markus Frankenbach +3
Recently, it has become possible to compute real-frequency four-point correlation functions of quantum impurity models using a multipoint extension of the numerical renormalization…
Reply to comment on "Controlled bond expansion for Density Matrix Renormalization Group ground state search at single-site costs"
Andreas Gleis, Jheng-Wei Li, Jan von Delft
We reply to McCulloch and Osborne's recent comment on our manuscript (Phys. Rev. Lett. 130, 246402 (2023)) on controlled bond expansion (CBE) for density matrix renormalization gro…
