Origin of misleading convergence in self-consistent many-electron theories: Fundamental aspects and practical implications
Herbert EÃl, Matthias Reitner, Evgeny Kozik +1
Self-consistent approaches in many-electron problems typically converge to an unphysical solution in strongly correlated regimes. By deriving the mathematical condition for the sta…
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…
Stabilizing the parquet problem
Herbert EÃl, Stefan Rohshap, Marcel Gievers +3
We systematically analyze the stability of the iterative solution of the parquet equations by studying the spectrum of the Jacobian associated with the commonly used damped fixed-p…
