Revolutionary Physics Discovery Challenges Quantum Theory
MIT physicists have discovered that electrons in pentalayer graphene can exhibit fractional charges without the presence of a magnetic field, a phenomenon termed the "fractional quantum anomalous Hall effect." This groundbreaking finding, explained through new theoretical models, suggests that electron interactions in confined two-dimensional spaces can lead to novel quantum states. The research, published in Physical Review Letters, provides a new mechanism for understanding fractional electron phenomena and opens up possibilities for future experiments in quantum physics.
