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 …

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 …

Vortices are the hallmarks of hydrodynamic flow. Strongly interacting electrons in ultrapure
conductors can display signatures of hydrodynamic behaviour, including negative non-local …

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 …

Plasmons, collective oscillations of electron systems, can efficiently couple light and electric
current, and thus can be used to create sub-wavelength photodetectors, radiation mixers …

The field of two-dimensional (2D) materials-based nanophotonics has been growing at a
rapid pace, triggered by the ability to design nanophotonic systems with in situ control …

Fermi liquids respond differently to perturbations depending on whether their frequency is
higher (collisionless regime) or lower (hydrodynamic regime) than the interparticle collision …

Thermally excited electrons and holes form a quantum-critical Dirac fluid in ultraclean
graphene and their electrodynamic responses are described by a universal hydrodynamic …

We study hydrodynamic and ballistic transport regimes through nonlocal resistance
measurements and high-resolution kinetic simulations in a mesoscopic structure on a high …

Two-dimensional electron systems subjected to a perpendicular magnetic field absorb
electromagnetic radiation via cyclotron resonance (CR). Here we report a qualitative …
