Chiral Phonons Coupled to Spin-Split Bands in Altermagnetic CrSb and MnTe
Armando Consiglio, Maximilian Ãnzelmann, Giancarlo Panaccione +1
Altermagnets exhibit momentum-dependent spin splitting without net magnetization, providing a unique platform where magnetic order, electronic structure and lattice dynamics intert…
Observation of spin-free interatomic orbital angular momentum in a chiral crystal
Dongjin Oh, Sungsoo Hahn, Chiara Pacella +4
The inherent spin-orbit interaction of electrons inevitably couples spin to the orbital angular momentum (OAM), posing a fundamental challenge to spin-free orbital transport. Here,…
p-Wave Orbital Angular Momentum Texture in a Chiral Crystal
Dongjin Oh, Chiara Pacella, Xiangyu Luo +8
The spin and orbital angular momentum (SAM and OAM) are conceptually analogous, yet their roles in condensed matter systems have not been often treated on equal footing. While SAM…
Observation and Control of Moiré-Tailored Topological Dirac States
R. Ganser, M. P. T. Masilamani, B. Geldiyev +6
Moiré heterostructures provide a powerful framework for tailoring electronic band structures via controlled long-range periodic superlattice potentials. Beyond widely studied moir…
Tunable Electronic Correlations in 135-Kagome Metals
Matteo Crispino, Niklas Witt, Stefan Enzner +4
Kagome metals exhibit rich correlated-electron physics, yet a systematic understanding of the degree of correlation across transition-metal species remains elusive. Using density-f…
Chiral topological superconductivity in hole-doped Sn/Si(111)
Matthew Bunney, Lucca Marchetti, Domenico Di Sante +2
A third monolayer of tin atoms on the semiconductor substrate Si(111) has been shown to become superconducting upon six to ten percent hole doping. Experiments have reported promis…
