Electron hydrodynamics

In different environments, electrons move through materials in drastically different ways. Sometimes, they can move like fluids through water pipes. But this is not so common, it requires a balance between electron-impurity and electron-electron scattering that can happen in certain temperature ranges in high-mobility materials like graphene. We study aspects of the transitions in transport regimes with changing conditions.
