Orbital Hall Effect in Weyl Semimetals from quantum geometric band interference
Chiara Pacella, Maximilian Ünzelmann, Ahmed Osman +4
Orbital angular momentum (OAM) transport in solids, prominently manifested in the orbital Hall effect, has emerged as a fundamental phenomenon that can decisively exceed its spin-b…

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 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,…
