Deskripsi
The ultra-quantum limit refers to the high magnetic-field regime where electrons are confined to the lowest Landau level and is most easily reached in topological semimetals due to their low carrier density. Here, the authors study this regime in the Dirac semimetal ZrTe5 and find evidence for a Lifshitz transition at moderate field, leading to the emergence of a 1D-Weyl band structure at high field.
