Exact downfolding and its perturbative approximation

Jonas B. Profe, Jakša Vučičević, P. Peter Stavropoulos +3

Solving the many-electron problem, even approximately, is one of the most challenging and simultaneously most important problems in contemporary condensed matter physics with vario…

Microscopic origin of the magnetic interactions and their experimental signatures in altermagnetic La $_{2}$ O $_{3}$ Mn $_{2}$ Se $_{2}$

Laura Garcia-Gassull, Aleksandar Razpopov, Panagiotis Peter Stavropoulos +2

Altermagnets (AM) are a recently introduced type of magnets, with no net magnetization like antiferromagnets, but displaying a non-relativistic Zeeman splitting in reciprocal space…

Altermagnetic splitting of magnons in hematite ( $α$ -Fe $_{2}$ O $_{3}$ )

Rhea Hoyer, P. Peter Stavropoulos, Aleksandar Razpopov +3

We develop a four-sublattice spin-wave theory for the $g$ -wave altermagnet candidate hematite ( $α$ -Fe $_{2}$ O $_{3}$ ), considering both its easy-axis phase below and its weak ferromagnet…
