Summary

Story summary

Researchers studying twisted bilayer and trilayer graphene show that heavy and light electrons coexist, influenced by impurities.
They identify two distinct phase transitions, one producing paired electrons and the other localized configurations.
Analytical calculations and numerical simulations confirm these findings and the formation of a pseudogap in spectroscopic measurements.
The work advances understanding of correlated electron behavior and opens avenues to study novel quantum phenomena in multilayer materials.
