2026.06.22. A new paper published in PRB: Interplay between orbital magnetism and quantum geometry in solids
GO-LAB published a new paper on the role of quantum geometry in orbital angular momentum. Here, we develop a gauge-covariant description of the orbital magnetism for multi-band electron systems and implement the formalism in our home-built code ORBITRANS, which is also interfaced with the community codes WANNIER90 and FLEUR.
This work is done in collaboration within the Center for Quantum Dynamics of Angular Momentum (Hojun Lee, Insu Baek, Hyun-Woo Lee, Dongwook Go) and with Jülich Research Centre (Mirco Sastges, Yuriy Mokrousov).

2026.02.18. A new paper in PRL: Local violation of Onsager's reciprocity
In collaboration with Prof. Kazuya Ando's group at Keio University in Japan, GO-LAB published a new article demonstrating local violation of Onsager's reciprocity for the first time. While this is a universal behavior for any coupled responses, we find that the violation is particularly pronounced in the orbital Hall effects, as predicted by Dongwook's theory (arXiv:2407.00517).
