Boundary phases and thermodynamics of the Kondo spin- chain: from overscreened Kondo to boundary-bound states
Abay Zhakenov, Pradip Kattel, Andreas Gleis +1
We study a spin- impurity coupled to the boundary of a strongly correlated spin- Takhtajan--Babujian chain, an integrable model whose low-energy physics is described by…
Interplay of spin-orbit coupling, crystal field splitting and correlations: a ghost rotationally invariant slave boson treatment
Xue Sun, Walber Hugo Brito, Andreas Gleis +4
We investigate the interplay of spin-orbit coupling, crystal field splittings, and electronic correlations in the Hubbard-Kanamori model within the recently formulated gho…
Dynamical scaling near the pseudogap quantum critical point of the two-dimensional Hubbard model
Mathias Pelz, Gabriel Kotliar, Jan von Delft +1
We study dynamical scaling in the quantum-critical fan of the pseudogap-metal to Fermi-liquid transition of the two-dimensional Hubbard model. Using a four-patch dynamical cluster…
Quantum criticality in the two-dimensional Hubbard model
Mathias Pelz, Gabriel Kotliar, Jan von Delft +1
We study the normal-state, doping-driven phase diagram of the square-lattice Hubbard model using the dynamical cluster approximation combined with the numerical renormalization gro…
Symmetric estimator for discrete self-energy of discrete many-body systems
Aleksandrs Zacinskis, Frank T. Ebel, Mathias Pelz +5
We derive a discrete spectral representation of the single-particle self-energy using a discrete evaluation of Kugler's symmetric improved estimator. Our construction can be used o…
Topological Kondo Insulator from Spin Loop Currents
Andreas Gleis, Kevin Lucht, Po-Jui Chen +3
We demonstrate that interacting electrons in AB-stacked realize a topological Kondo insulator at hole filling per moiré unit cell. In the pre…
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…
