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…
Giant Shubnikov-de Haas Oscillations with V-Shaped Minima in a High-Mobility Two-Dimensional Electron Gas: Experiment and Phenomenological Model
E. Yu. Zhdanov, M. V. Budantsev, D. I. Sarypov +3
Giant Shubnikov-de Haas oscillations (SdHO) with V-shaped minima are experimentally studied in a high-mobility two-dimensional electron gas based on GaAs/AlGaAs heterostructures. A…
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…
