The team attributes this to 'reentrant Landau levels' arising from the interplay of electron spin, orbital motion, and strong spin-orbit coupling, rather than many-body electron interactions. A single-particle model based on a three-dimensional Dirac Hamiltonian reproduced the observed behavior, helping resolve prior contradictory reports about ZrTe₅ oscillations by showing that carrier density and Fermi-surface size determine which pattern appears. The findings position ZrTe₅ as a platform for exploring further exotic topological phases, including those tied to Weyl quasiparticles. ## Full article daily.dev links to this article rather than hosting it.
