Abstract
In the emerging field of orbitronics, the orbital Hall effect stands out as one of the most important transport phenomena of orbital angular momentum. Here, the authors present a highly efficient and accurate first-principles method to compute the orbital Hall effect by Wannier interpolation and point out the crucial role of the anomalous position for the gauge-covariant description. The work guides the ongoing experimental efforts on the quantitative measurement of orbital currents.
