As high-quality single-crystal materials used in electronic devices approach the microscale
and nanoscale, charge-transport phenomena in these devices result in inhomogeneous …

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

Electron–electron interactions in high-mobility conductors can give rise to transport
signatures resembling those described by classical hydrodynamics. Using a nanoscale …

We measure electron transport through point contacts in an electron gas in AlGaAs/GaAs
heterostructures and graphene for a range of temperatures, magnetic fields, and electron …

The hydrodynamic behavior of electron fluids in a certain range of temperatures and
densities is well established in graphene and in two-dimensional semiconductor …

Band inversion accompanied by the emergence of gapless and helical edge states at the
boundary is a hallmark of 2D topological insulators. However, a recent experiment reports …

It has been established that the Coulomb interactions can transform the electron gas into a
viscous fluid. This fluid is realized in a number of platforms, including graphene and two …

Driven by the pursuit of high-performance electronic devices and the exploration of quantum
phenomena, research into two-dimensional (2D) systems and materials, has unveiled their …

Recently, a wide family of electronic orders was unveiled in graphene flat bands, such as
spin-and valley-polarized phases as well as nematic momentum-polarized phases …

It is shown that the ideal boundary between a perfectly conducting electrode and electron
liquid state acts as a contact whose conductance per unit area is higher than the …
