Quantum Hydrodynamics: Nodal-line Semimetals

This lecture by the instructor covers the unbounded hydrodynamics in nodal-line semimetals, focusing on the behavior of quantum fluids and the shear viscosity properties. It delves into the observation of the Dirac fluid, breakdown of the Wiedemann-Franz law in graphene, and electron transport phenomena. The discussion extends to the quantum kinetic theory for nodal-line semimetals, the ratio between shear viscosity and entropy, and the implications of screening effects. The lecture concludes with insights on transport signatures for hydrodynamic behavior in nodal-line semimetals and the potential for quantum turbulence.
