Dynamic Strain Controls Quantum Geometry in 2D Materials

This paper presents a novel approach to controlling quantum geometric properties in 2D materials using dynamic strain. The ability to modulate Berry curvature and generate a pseudo-electric field in real-time opens up new possibilities for manipulating electronic transport and exploring topological phenomena. The experimental demonstration of a dynamic strain-induced Hall response is a significant achievement.

• •Demonstrates dynamic modulation of Berry curvature and its moments.
• •Generates a pseudo-electric field using time-dependent strain.
• •Provides a new pathway for controlling quantum geometry on demand.
• •Opens avenues for probing topological properties without external electric fields.
