On Degeneracies of Density, Magnetic, and Pairing Responses: How Competing Orders Echo Underlying Symmetries in the Hubbard Model
Michael Meixner, Herbert EÃl, 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…
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…
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.…
