Universal intrinsic orbital dynamics from Berry curvature in electronic two-band systems

Phys. Rev. B 112, 054441 (2025)

DOI: https://doi.org/10.1103/42mj-sh8x

This study reveals that the orbital angular momentum and its transport in electronic systems are generally determined solely by the band energy and the Berry curvature. The work was carried out independently, and I am grateful to Prof. Hyun-Woo Lee for his encouragement throughout the process.

Congratulations!

Celebrating 100 Citations and Looking Ahead (18th Aug. 2025)

Google Scholar indicates that my research papers have reached one hundred citations. Since 2020, during my second year of graduate school, through 2025, my first year as a postdoctoral researcher, I have published and uploaded nine papers. I am now preparing to submit another work on squeezed bosons, and my project on cavity quantum electrodynamics is also nearing completion. I am delighted to see my research progressing steadily and excited to move forward at my next affiliation in Alberta. 

I sincerely appreciate the support and collaboration of my research colleagues and advisors.

Moving to Alberta, Canada (September 2025)

I will be joining the Department of Physics at the University of Alberta as a postdoctoral researcher starting September 8, 2025, supported by a Quantum Horizons Alberta (QHA) Fellowship.

I have now purchased my flight ticket.

I am very excited about this opportunity and look forward to the experience.

Diverging entanglement of critical magnons in easy-axis antiferromagnets

Phys. Rev. B 111, 094402 (2025)

DOI: https://doi.org/10.1103/PhysRevB.111.094402

This study theoretically investigates magnons in anisotropic antiferromagnets under a magnetic field, revealing that magnon entanglement is critically enhanced near the transition between noncollinear and collinear spin orders. 

Congratulations!

Orbital Edelstein effect of electronic itinerant orbital motion at edges

Phys. Rev. B 110, 134436 (2024)

DOI: https://doi.org/10.1103/PhysRevB.110.134436

This study demonstrates the universal generation of orbital magnetization at the edges, driven by the curly-whirly motion along the zigzag boundaries.
