Altermagnetism from a Cu-Fe Lieb Lattice in FeSe/Cuprate Heterostructures
Ying Li, Augustin Davignon, Peng Rao +4
Realizing altermagnetism in high- cuprate-based systems would provide a direct route for studying spin-split electronic bands in the absence of net magnetization and investiga…
Microscopic Emergence of Ancilla Lattice Physics in the Emery Model
Mikołaj Walicki, Johannes Knolle, Krzysztof Wohlfeld
We derive a controlled low-energy effective theory for the three-band Emery model on the Lieb lattice near (n=2) filling. Starting from the positive charge-transfer regime, a seque…
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 range…
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…
