Jia-Xin Xiong

Research Interests:

• Quantum materials with exotic electronic and magnetic properties
• Spintronics in nonmagnetic and antiferromagnetic materials, including spin-orbit coupling and non-relativistic spin splitting
• Symmetry breaking effects and their impact on metallic and insulating behaviors, especially involving transition-metal materials
• First-principles electronic structure calculations
• Stability and electronic properties of halide perovskites 

His work combines symmetry analysis, magnetic group theory, and density functional theory to predict and understand emergent phenomena in quantum materials.
