Dynamical Orbital Angular Momentum Induced by Circularly Polarized Phonons
Dapeng Yao, Dongwook Go, Yuriy Mokrousov +1
We show that the orbital angular momentum (OAM) of electrons is dynamically induced by circularly polarized phonons. The induced OAM originates from the adiabatic evolution in whic…
Anatomy of the modern theory of orbital magnetism from first-principles: term-by-term analysis in the gauge-covariant formalism
Hojun Lee, Insu Baek, Mirco Sastges +3
We present an in-depth analysis of the orbital magnetism by means of the so-called modern theory based on the Berry phase across distinct classes of materials-d transition metals,…
Coexistence and tunability of orbital and spin Hall effects in RuO
Lishu Zhang, Mahmoud Zeer, Dongwook Go +8
Altermagnetic materials, especially RuO, have recently attracted considerable attention for their unique magnetic properties and energy-efficient spintronic applications. Howev…
Modern Approach to Orbital Hall Effect Based on Wannier Picture of Solids
Mirco Sastges, Insu Baek, Hojun Lee +3
The orbital Hall effect (OHE) and its key figure of merit, the orbital Hall conductivity (OHC), are central to the emerging field of orbitronics. The OHC is conventionally computed…
Giant orbital magnetoresistance in the antiferromagnet CoO driven by dynamic orbital angular momentum interaction
Christin Schmitt, Sachin Krishnia, Edgar Galindez-Ruales +12
Recent predictions of orders of magnitude larger orbital current effects compared to spin currents have attracted significant interest. However, the full potential of giant orbital…
Interfacial orbital transmission, conversion, and mechanical torque in metals
Chi Sun, Dongwook Go, Yuriy Mokrousov +2
Interfacial orbital transport remains far less understood than its bulk counterpart despite its central role in orbitronic experiments. Here, we theoretically investigate the trans…
