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…

Transient localization from fractionalization: vanishingly small heat conductivity in gapless quantum magnets

Shi Feng, Penghao Zhu, Johannes Knolle +1

Several candidate materials for gapless quantum spin liquids exhibit a vanishing thermal conductivity, which is at odds with theoretical predictions. Here, we show that a suppresse…
