Electrical magnetochiral anisotropy and quantum metric in chiral conductors

Published in 2D Materials, 2024

We reveal a quantum geometric origin of EMCA using a chiral rectangular lattice model, showing that the quantum metric plays a key role in enhancing the nonlinear response.

Hybrid-order topology in unconventional magnets of Eu-based Zintl compounds

Published in Physical Review B, 2024

We reveal that Eu-based Zintl compounds host a hybrid-order topological phase with coexisting gapless Dirac surface states and chiral hinge modes, exhibiting surface-dependent quantum geometry.

Three-dimensional higher-order saddle-point-induced flatbands in Co-based kagome metals

Published in Physical Review Research, 2024

We report two types of 3D higher-order saddle points in Co-based kagome metals with strongly enhanced density of states and an extended flatband near the Fermi level.

Designing Strong and Broadband Nonreciprocal Thermal Radiation in Magnetic Topological Materials

Published in arXiv preprint, 2026

We predict a series of magnetic topological materials for magnet-free nonreciprocal thermal radiation in the infrared, finding strong and broadband nonreciprocity in magnetic Weyl semimetals (e.g., Co₃Sn₂S₂) and establishing universal design rules tying nonreciprocity to the anomalous Hall response and optical loss.

Residual orbital magnetization governs the anomalous Hall effect in altermagnets

Published in arXiv preprint, 2026

We show that the small residual orbital magnetization—long dismissed as irrelevant—governs the intrinsic anomalous Hall effect in altermagnets via the generalized Středa relation, and reveal a crystal-field/spin-orbit mechanism that generates this net moment in MnTe-type altermagnets without invoking Dzyaloshinskii-Moriya interaction.
