Evidence for a field-induced Lifshitz transition in the Weyl semimetal CeAlSi

M. M. Piva, T. Helm, J. C. Souza +4

The Weyl semimetal CeAlSi crystallises in the noncentrosymmetric tetragonal space group $I{4}_{1}md$ and exhibits ferromagnetic order below 8 K, thereby breaking both spatial inversion…
