Explore the intricacies of heat propagation in liquid helium-3 through this 34-minute conference talk by Kamran Behnia from ESPCI Paris. Delivered as part of the "Electron Correlations beyond the Quasiparticle Paradigm: Theory and Experiment" conference at the Kavli Institute for Theoretical Physics, delve into cutting-edge research on materials that challenge the Fermi-liquid paradigm. Gain insights into non-Fermi liquid observations, electron transport beyond quasiparticles, and the nature of Cooper pairing in systems without well-defined quasiparticles. Discover how this presentation contributes to the broader discussion on quantum matter and the application of theoretical and experimental approaches in understanding complex electron correlations.
