Theoretical physicist uncovers how twisting layers of a material can generate mysterious electron-path-deflecting effect

Summary

89% Informative

University of Pennsylvania's Ritesh Agarwal and Eugene Mele studied spirally stacked tungsten disulfide crystals.

By twisting these layers, light could be used to manipulate electrons.

The result is analogous to the Coriolis force, which curves the paths of objects in a rotating frame, like how wind and ocean currents behave on Earth .

In this system, the moiré length scale created by the twist is on par with the wavelength of light.

When light interacted with the twisted structure, the team observed complex wavefunctions and behaviors not seen in regular two -dimensional materials.

This result ties into the concept of "higher-order quantum geometric quantities" like Berry curvature multipoles, which provide insight into material's quantum states and behaviors.
