Explore a 33-minute conference talk on heavy quasiparticles and cascades without symmetry breaking in twisted systems, presented by Elena Bascones from CSIC. Delivered as part of the "Electron Correlations beyond the Quasiparticle Paradigm: Theory and Experiment" conference at the Kavli Institute for Theoretical Physics, this presentation delves into cutting-edge research on materials that challenge the Fermi-liquid paradigm. Gain insights into the latest theoretical and experimental findings reshaping our understanding of quantum matter, including discussions on electron transport, Planckian limits on scattering, and Cooper pairing without quasiparticles. Discover how this talk contributes to the broader conference goal of distinguishing between phenomena explicable through conventional methods and those requiring novel approaches beyond the quasiparticle framework.
