    Entropic evidence for a Pomeranchuk effect in magic-angle graphene

    In the 1950s, Pomeranchuk1 predicted that, counterintuitively, liquid 3He may solidify on heating. This effect arises owing to high excess nuclear spin entropy in the solid phase, where the atoms are spatially lo...

    Visualizing Poiseuille flow of hydrodynamic electrons

    Hydrodynamics, which generally describes the flow of a fluid, is expected to hold even for fundamental particles such as electrons when inter-particle interactions dominate1. Although various aspects of electron ...

    Simultaneous voltage and current density imaging of flowing electrons in two dimensions

    A variety of physical phenomena associated with nanoscale electron transport often results in non-trivial spatial voltage and current patterns, particularly in nonlocal transport regimes. While numerous techni...
