Emergent Topology from Nonlocal Electronic Correlations in One Dimension
Félix Fossati, Erik Linnér, Evgeny A. Stepanov
We demonstrate that electronic correlations in low-dimensional systems can induce topological phases starting from a topologically trivial noninteracting band structure. Using an a…
Coexistence of -wave superconductivity and phase separation in the half-filled extended Hubbard model with attractive interactions
E. Linnér, C. Dutreix, S. Biermann +1
Understanding competing instabilities in systems with correlated fermions remains one of the holy grails of modern condensed matter physics. Among the fermionic lattice models used…
Multi-channel fluctuating field approach to competing instabilities in interacting electronic systems
E. Linnér, A. I. Lichtenstein, S. Biermann +1
Systems with strong electronic Coulomb correlations often display rich phase diagrams exhibiting different ordered phases involving spin, charge, or orbital degrees of freedom. The…
Ensemble Green's function theory for interacting electrons with degenerate ground states
Erik Linnér, Ferdi Aryasetiawan
An ensemble Green's function formalism, based on the von Neumann density matrix approach, to calculate one-electron excitation spectra of a many-electron system with degenerate gro…
