Altermagnetic phase transition in a Lieb metal
arXiv:2412.14251 · doi:10.1103/2g3v-z76q
Abstract
We analyze the phase transition between a symmetric metallic parent state and itinerant altermagnetic order. The underlying mechanism we reveal in our microscopic model of electrons on a Lieb lattice does not involve orbital ordering, but derives from sublattice interference.
