Welcome. I am a postdoctoral researcher working at the intersection of spintronics and quantum information science. My work explores the nonequilibrium dynamics of electron spin and orbital motion in low-dimensional systems, alongside the coherent control of magnons and their nonreciprocity for quantum state transfer. I’m driven by the transformative potential of these fields to advance technologies like energy-efficient devices and quantum computing, which can create lasting positive impacts on society.
My research seeks to uncover the fundamental principles governing low-dimensional quantum systems, particularly through the interplay of spin, orbital, and topological properties. By building a foundational understanding, I aim to contribute to quantum information science and drive innovative technologies that address global challenges.
My current research centers on the quantum properties of propagating magnons, investigating magnon-phonon coupling for quantum transduction and the integration of magnetic materials with superconducting quantum devices. I also explore how topology and symmetry shape the magnetic and transport properties of low-dimensional systems and how they influence spin/orbital dynamics in spintronic devices.
In my research, I employ a multifaceted approach to connect theory with real-world applications:
1. Theoretical Modeling: Using simplified models and the tight-binding method, I predict phenomena and their underlying mechanisms in general systems.
2. First-Principles Calculations: I analyze real materials to uncover specific physical behaviors, refining theoretical predictions.
3. Experimental Collaboration: By working closely with experimental groups, I validate predictions against empirical data, bridging theory and reality.
Thank you for visiting my homepage. I hope my research sparks your curiosity. Please feel free to reach out with any questions or to discuss potential collaborations.
