Network model for magnetic higher-order topological phases
Hui Liu, Ali G. Moghaddam, Daniel Varjas +1
We propose a network-model realization of magnetic higher-order topological phases (HOTPs) in the presence of the combined space-time symmetry -- the product of a…

The geometry of the Hermitian matrix space and the Schrieffer--Wolff transformation
Gergő Pintér, György Frank, Dániel Varjas +1
In quantum mechanics, the Schrieffer--Wolff (SW) transformation (also called quasi-degenerate perturbation theory) is known as an approximative method to reduce the dimension of th…

Stability of Weyl node merging processes under symmetry constraints
Gabriele Naselli, György Frank, Dániel Varjas +4
Changes in the number of Weyl nodes in Weyl semimetals occur through merging processes, usually involving a pair of oppositely charged nodes. More complicated processes involving m…
