Explore the groundbreaking physics of fractional charge phenomena through this Stanford Physics lecture examining how electron-electron interactions lead to charge fractionalization. Discover the fractional quantum Hall effect (FQH) and its lattice analog, the fractional quantum anomalous Hall effect (FQAH), which operates without magnetic fields. Learn about transport measurements establishing FQAH in twisted MoTe2 bilayers and understand how high-energy photons can probe fractional excitations with energies three orders of magnitude lower. Examine the observation of the Jain sequence of fractional states and investigate a newly discovered quasi-particle complex called anyon-trions. Gain insights into how these findings advance our understanding of charge fractionalization and anyonic physics in zero magnetic field conditions, opening new pathways for exploring exotic quantum phenomena and their potential applications in quantum computing and condensed matter physics.
