Transport Detection of Whirlpools in GaAs Electron Liquid
Dmitry A. Egorov, Dmitriy A. Pokhabov, Evgeny Yu. Zhdanov +3
We report the formation of large-scale steady-state whirlpools in a GaAs-based two-dimensional electron liquid and demonstrate them by straightforward transport measurements. A whi…
Electron Tesla valve
Daniil I. Sarypov, Dmitriy A. Pokhabov, Arthur G. Pogosov +3
In solids, frequent electron-electron collisions can induce collective, fluid-like electron transport. While this regime offers a powerful framework for exploring many-body phenome…
Nanomechanical detection of vortices in an electron fluid
Andrey A. Shevyrin, Askhat K. Bakarov, Arthur G. Pogosov
Electron vortices are the quintessential signature of a viscous electron fluid. For decades, their detection relied on indirect transport measurements with persistently debated int…
Slip electron flow in GaAs microscale constrictions
Daniil I. Sarypov, Dmitriy A. Pokhabov, Arthur G. Pogosov +4
Hydrodynamic electron transport in solids, governed by momentum-conserving electron-electron collisions, offers a unique framework to explore collective phenomena. Within this fram…
The role of small-angle electron-electron scattering in transverse magnetic focusing experiment
Dmitry A. Egorov, Dmitriy A. Pokhabov, Evgeny Yu. Zhdanov +4
We demonstrate the crucial role of small-angle scattering in transverse magnetic focusing (TMF) in ballistic GaAs/AlGaAs heterostructures. Measurements in various samples show that…
