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…

Weyl nodes in CeBiPd revealed by dynamical mean-field theory
Martin Braß, Jan M. Tomczak, Karsten Held
Experimental studies have found unusual transport properties in CeBiPd which are potentially a consequence of the interplay between band-structure topology and electron…

Weyl points and spin-orbit coupling in copper-substituted lead phosphate apatite
Martin Braß, Liang Si, Karten Held
We study the impact of spin-orbit coupling on the topological band-properties of copper-substituted lead phosphate apatite using a combination of group-theoretical analysis and ful…
