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

Hydrodynamic approach to two-dimensional electron systems
BN Narozhny - La Rivista del Nuovo Cimento, 2022 - Springer
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 …

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

Hydrodynamic electronic transport
L Fritz, T Scaffidi - Annual Review of Condensed Matter Physics, 2024 - annualreviews.org
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 …

Large- theory of critical Fermi surfaces. II. Conductivity
A Fermi surface coupled to a scalar field can be described in a 1/N expansion by choosing
the fermion-scalar Yukawa coupling to be random in the N-dimensional flavor space, but …
