Generic interacting many-body quantum systems are believed to behave as classical fluids
on long time and length scales. Due to rapid progress in growing exceptionally pure crystals …

The last few years have seen an explosion of interest in hydrodynamic effects in interacting
electron systems in ultra-pure materials. One such material, graphene, is not only an …

Hydrodynamics, which generally describes the flow of a fluid, is expected to hold even for
fundamental particles such as electrons when inter-particle interactions dominate. Although …

The “flow” of electric currents and heat in standard metals is diffusive with electronic motion
randomized by impurities. However, for ultraclean metals, electrons can flow like water with …

Electrical resistance usually originates from lattice imperfections. However, even a perfect
lattice has a fundamental resistance limit, given by the Landauer conductance caused by a …

The most recognizable feature of graphene's electronic spectrum is its Dirac point, around
which interesting phenomena tend to cluster. At low temperatures, the intrinsic behaviour in …

In the past few decades, numerous heat conduction models extending beyond Fourier's
have been developed to account for large gradients, fast phenomena, wave propagation …

Graphene near charge neutrality is expected to behave like a quantum-critical, relativistic
plasma—the “Dirac fluid”—in which massless electrons and holes collide at a rapid rate. We …

The sensitivity of charge, heat, or momentum transport to the sample geometry is a hallmark
of viscous electron flow. Therefore hydrodynamic electronics requires a detailed …

The charge carriers in a material can, under special circumstances, behave as a viscous
fluid. In this work, we investigated such behavior by using scanning tunneling potentiometry …
