Hydrodynamic Effects in Interacting Fermi Electron Jets
Hydrodynamic Effects in Interacting Fermi Electron Jets
We theoretically study hydrodynamic phenomena originating from electron-electron collisions in a two-dimensional Fermi system. We demonstrate that an electron beam sweeping past an aperture creates a pumping effect, attracting carriers from this aperture. This pumping effect originates from the specific electric potential distribution induced by the injected electrons. In the …
