Altermagnetism from a Cu-Fe Lieb Lattice in FeSe/Cuprate Heterostructures
Ying Li, Augustin Davignon, Peng Rao +4
The paper proposes that FeSe/cuprate heterostructures with a twisted Cu-Fe arrangement can host altermagnetism, producing spin‑split electronic bands without net magnetization, and…
Microscopic Emergence of Ancilla Lattice Physics in the Emery Model
MikoÅaj Walicki, Johannes Knolle, Krzysztof Wohlfeld
The paper derives a low‑energy effective theory for the three‑band Emery model on a Lieb lattice, showing how an ancillary lattice emerges and identifying the microscopic condition…
Signatures of Topological Magnon Edge States in THz Spectroscopy and Cavity Response
Ipsika Mohanty, Johannes Knolle, Silvia Viola Kusminskiy
Topological magnon insulators (TMIs) have emerged as promising platforms for low-energy spin-based information processing, due to their non-trivial bulk magnon topology and robust,…
GHz non-reciprocal optical conductivity in hematite (-)
Peng Rao, Johannes Gröbmeyer, P. Peter Stavropoulos +5
We study the non-reciprocal properties of the iron oxide -FeO (hematite) in the canted easy-plane antiferromagnetic phase, specifically in the GHz to THz frequency rang…
Magnetic Bloch Oscillations in Odd-Wave Magnets and the Nonlinear Edelstein Effect
Jonas Habel, Johannes Knolle
Bloch oscillations (BOs) are a quantum phenomenon in which electrons subjected to an electric field in a periodic potential exhibit an oscillating current without a net drift. In r…
Fate of Topological Dirac Magnons in van der Waals Ferromagnets at Finite Temperature
Rintaro Eto, Ignacio Salgado-Linares, Masahito Mochizuki +2
Dirac magnons, the bosonic counterparts of Dirac fermions in graphene, provide a unique platform to explore symmetry-protected band crossings and quantum geometry in magnetic insul…
