Hydrodynamic flow of electrons
When we talk about the flow of electric currents, we unwittingly carry in our language the early idea that electrons in a metal behave akin to a liquid. This analogy ultimately fails as the momentum of electrons in a crystal is not conserved. Yet materials with strong electronic interactions and long mean free paths can exhibit a quasi-conserved electronic momentum, starting an experimental hunt for hydrodynamic behavior of electrons in solids.
