In the world of materials science and condensed matter physics, the behavior of electrons is pivotal. Typically, electrons act like free particles, roaming through metals with a seemingly erratic motion akin to billiard balls colliding in chaos. When these charged particles encounter obstacles, they scatter, losing energy and generating friction. However, an intriguing phenomenon occurs
