Summary

Story summary

Researchers report that graphene's electronic properties under light show phenomena such as the light-induced anomalous Hall effect and Floquet states.
They also observe the merging of Dirac points and the engineering of Dirac states under electromagnetic waves.
The work includes observation of Floquet-Bloch states and studies of graphene transport in nonequilibrium conditions.
These findings advance understanding of graphene's electronic properties and its potential applications in quantum materials.

History

Historical Context

In 2004, Andre Geim and Konstantin Novoselov successfully isolated graphene, a single layer of carbon atoms, using a technique known as micromechanical cleavage. Their groundbreaking work earned them the Nobel Prize in Physics in 2010. Graphene's exceptional properties, including an electron mobility exceeding 200,000 cm²/Vs, have since spurred extensive research, promising revolutionary advancements in electronics and materials science.
