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…
Spontaneous Crystal Thermal Hall Effect in Insulating Altermagnets
Rhea Hoyer, Rodrigo Jaeschke-Ubiergo, Kyo-Hoon Ahn +2
We show that magnetic insulators with a collinear and compensated order can exhibit a thermal Hall effect even at zero magnetic field if they have altermagnetic symmetries. We pred…
Topological Hybrids of Magnons and Magnon Bound Pairs
Alexander Mook, Rhea Hoyer, Jelena Klinovaja +1
We consider quantum condensed matter systems without particle-number conservation. Since the particle number is not a good quantum number, states belonging to different particle-nu…
