On Degeneracies of Density, Magnetic, and Pairing Responses: How Competing Orders Echo Underlying Symmetries in the Hubbard Model
Michael Meixner, Herbert Eßl, Matthias Reitner +2
Strongly correlated electron systems often display competing or even intertwined ordering tendencies, hinting to extremely close or degenerate many-electron energies. While degener…
Beyond the conventional Emery model: crucial role of long-range hopping for cuprate superconductivity
Eric Jacob, M. O. Malcolms, Viktor Christiansson +6
The Emery model is the quintessential model for cuprate superconductors. In his eponymous paper, Emery only considered the next-nearest-neighbor oxygen-copper hopping. Later, also…
Two distinct quantum critical behaviors in the doped two-dimensional periodic Anderson model
M. Kitatani, T. Schäfer, A. A. Katanin +2
We study quantum criticality in the doped two-dimensional periodic Anderson model with the hybridization acting as a tuning parameter. Employing the dynamical vertex approximation…
Rise and Fall of the Pseudogap in the Emery model: Insights for Cuprates
M. O. Malcolms, Henri Menke, Yi-Ting Tseng +4
The pseudogap in high-temperature superconducting cuprates is an exotic state of matter, displaying emerging Fermi arcs and a momentum-selective suppression of states upon cooling.…
Disentangling real space fluctuations: the diagnostics of metal-insulator transitions beyond single-particle spectral functions
Michael Meixner, Marcel Krämer, Nils Wentzell +4
The destruction of metallicity due to the mutual Coulomb interaction of quasiparticles gives rise to fascinating phenomena of solid state physics such as the Mott metal-insulator t…
Hot QCD White Paper
M. Arslandok, S. A. Bass, A. A. Baty +170
Hot QCD physics studies the nuclear strong force under extreme temperature and densities. Experimentally these conditions are achieved via high-energy collisions of heavy ions at t…
The Present and Future of QCD
P. Achenbach, D. Adhikari, A. Afanasev +400
This White Paper presents the community inputs and scientific conclusions from the Hot and Cold QCD Town Meeting that took place September 23-25, 2022 at MIT, as part of the Nuclea…
Mott insulators with boundary zeros
Niklas Wagner, Lorenzo Crippa, Adriano Amaricci +9
The topological classification of electronic band structures is based on symmetry properties of Bloch eigenstates of single-particle Hamiltonians. In parallel, topological field th…
QCD Phase Structure and Interactions at High Baryon Density: Continuation of BES Physics Program with CBM at FAIR
D. Almaalol, M. Hippert, J. Noronha-Hostler +41
We advocate for an active US participation in the international collaboration of the CBM experiment that will allow the US nuclear physics program to build on its successful explor…
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…
Anisotropy of electronic correlations: On the applicability of local theories to layered materials
Benjamin Klebel, Thomas Schäfer, Alessandro Toschi +1
Besides the chemical constituents, it is the lattice geometry that controls the most important material properties. In many interesting compounds, the arrangement of elements leads…
Complementary views on electron spectra: From Fluctuation Diagnostics to real space correlations
O. Gunnarsson, J. Merino, T. Schäfer +3
We study the relation between the microscopic properties of a many-body system and the electron spectra, experimentally accessible by photoemission. In a recent paper [Phys. Rev. L…

Petra Pudleiner, Thomas Schäfer, Daniel Rost +3
We compute the self-energy for the half-filled Hubbard model on a square lattice using lattice quantum Monte Carlo simulations and the dynamical vertex approximation. The self-ener…
Dynamical vertex approximation in its parquet implementation: application to Hubbard nano-rings
A. Valli, T. Schäfer, P. Thunström +5
We have implemented the dynamical vertex approximation (DA) in its full parquet-based version to include spatial correlations on all length scales and in {\sl all} scattering ch…
