Emergent Composite-Fermion Luttinger Liquid at the Half-Filled Landau Level

Watch a physics seminar from Harvard CMSA's Topological Quantum Matter series where Prashant Kumar from the University of Chicago explores the half-filled Landau level in quantum Hall effect systems. Delve into numerical calculations of excitation spectra on infinite cylinders and discover evidence for an emergent composite-fermion Luttinger liquid state at low energies. Learn how this state differs from traditional electron behavior and understand the comparison between experimental results and quasi-1D composite fermion theory. Gain insights into this fascinating quantum phenomenon that challenges our understanding of non-Fermi liquid states and opens new directions for research in topological quantum matter.
