-RuCl intercalated into graphite: a new three-dimensional platform for exotic quantum phases
Aleksandar Razpopov, Shirin Mozaffari, Takahiro Matsuoka +5
Multilayer graphene with different stacking sequences has emerged as a powerful setting for correlated and topological phases. In parallel, progress in graphene heterostructures wi…
Phonon spectrum in the spin-Peierls phase of CuGeO
L. Spitz, A. Razpopov, S. Biswas +10
CuGeO has long been studied as a prototypical example of the spin-Peierls transition in a Heisenberg chain. Despite intensive investigation of this quasi-one-dimensio…
Microscopic origin of the magnetic interactions and their experimental signatures in altermagnetic LaOMnSe
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 (-FeO)
Rhea Hoyer, P. Peter Stavropoulos, Aleksandar Razpopov +3
We develop a four-sublattice spin-wave theory for the -wave altermagnet candidate hematite (-FeO), considering both its easy-axis phase below and its weak ferromagnet…
