Hello, and welcome to my homepage. I'm Mijin Lim, a postdoctoral researcher passionate about spintronics, orbitronics, and topological effects. I'm particularly interested in the nonequilibrium dynamics and mechanisms governing electron spin and orbital motion in low-dimensional systems, and how we can harness this knowledge to advance technology. Spintronics, with its focus on technological innovation, is a field I find immensely rewarding. I believe that contributing to its progress can have a significant positive impact on society.
My current research explores the interplay between topology and symmetry in low-dimensional systems. Using analytical theory and numerical simulations, I investigate their magnetic and transport properties. I'm also interested in how strong Coulomb interactions affect spin/orbital dynamics and spintronic devices.
My research approach often involves developing simplified models and employing the tight-binding method to predict phenomena and their underlying mechanisms in general systems. I also conduct first-principles calculations on real materials to analyze potential physical behaviors. To connect theory with reality, I collaborate with experimental groups, comparing our theoretical predictions with their empirical findings.
Thank you for visiting my homepage. I hope my research sparks your interest. Please feel free to reach out if you have any questions or would like to discuss potential collaborations.
