Linear Response in Topological Materials

Understand

The discovery of topological insulators and semimetals has opened up a new perspective to understand materials.

• Owing to the special band structure and enlarged Berry curvature, the linear responses are strongly enhanced in topological materials.
• The interplay of topological band structure and symmetries plays a crucial role for designing new materials with strong and exotic new electromagnetic responses and provides promising mechanisms and new materials for the next generation of technological applications.
• We review the fundamental concept of linear responses in topological materials from the symmetry point of view and discuss their potential applications.
