Mott insulating states with competing orders in the triangular lattice Hubbard model
Alexander Wietek, Riccardo Rossi, Fedor Šimkovic +6
The physics of the triangular lattice Hubbard model exhibits a rich phenomenology, ranging from a metal-insulator transition, intriguing thermodynamic behavior, and a putative spin…
Tracking the Footprints of Spin Fluctuations: A MultiMethod, MultiMessenger Study of the Two-Dimensional Hubbard Model
Thomas Schäfer, Nils Wentzell, Fedor Šimkovic +23
The Hubbard model represents the fundamental model for interacting quantum systems and electronic correlations. Using the two-dimensional half-filled Hubbard model at weak coupling…
Real-space cluster dynamical mean-field theory: Center focused extrapolation on the one- and two particle level
Marcel Klett, Nils Wentzell, Thomas Schäfer +4
We revisit the cellular dynamical mean-field theory (CDMFT) for the single band Hubbard model on the square lattice at half filling, reaching real-space cluster sizes of up to 9 x…
Topological edge states in the Su-Schrieffer-Heeger model subject to balanced particle gain and loss
Marcel Klett, Holger Cartarius, Dennis Dast +2
We investigate the Su-Schrieffer-Heeger model in presence of an injection and removal of particles, introduced via a master equation in Lindblad form. It is shown that the dynamics…
