Symmetric estimator for discrete self-energy of discrete many-body systems
Aleksandrs Zacinskis, Frank T. Ebel, Mathias Pelz +5
We derive a discrete spectral representation of the single-particle self-energy using a discrete evaluation of Kugler's symmetric improved estimator. Our construction can be used o…

Weyl nodes in CeRuSn studied by dynamical mean-field theory
Jorūnas Dobilas, Martin Brass, Frank T. Ebel +2
The heavy fermion compound CeRuSn was recently shown to exhibit a spontaneous nonlinear Hall effect, indicating its topological nature. This is consistent with the lack of…
