Vestigial altermagnetism
Peng Rao, Johannes Knolle
Interaction effects and fluctuations govern the phase diagram of systems with multiple competing phases. In particular, as individual phases are destroyed by increasing temperature…
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…
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…
Topological Triplons in the Pinwheel Valence Bond Solid on the Kagome Lattice
Laura Calonge-Martínez, Peng Rao, Frédéric Mila +1
We investigate the triplon excitations of the pinwheel valence-bond-solid phase on the deformed kagome lattice compound Rb2Cu3SnF12. Using bond-operator mean-field theory, we compu…
Proximate quantum spin liquids and Majorana continua in magnetically ordered Kitaev magnets
Peng Rao, Roderich Moessner, Johannes Knolle
We study the spin excitation spectra in magnetically ordered phases proximate to the Kitaev quantum spin liquid (KQSL). Although the low-energy universal features should be governe…
Current-tunable room temperature ferromagnetism and current-driven phase transitions
Jianping Guo, Peng Rao, Xinhao Huang +9
It is generally assumed that the application of a charge-current in ferromagnetic metals suppresses their ferromagnetic order through trivial Joule heating. Here, we demonstrate th…
Electric-current control of anomalous Hall effect
Jianping Guo, Gusthavo M. S. Brizolla, Peng Rao +10
We demonstrate robust and reversible electric-current control of the anomalous Hall effect (AHE) in a two-dimensional WTe2/Fe3GeTe2 (FGT) stack. Applying a current through Td-WTe2…
