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…
Electronic state back action on mechanical motion in a quantum point contact coupled to a nanomechanical resonator
Andrey A. Shevyrin, Askhat K. Bakarov, Alexander A. Shklyaev +1
In a nanomechanical resonator coupled to a quantum point contact, the back action of the electronic state on mechanical motion is studied. The quantum point contact conductance cha…
Temperature Dependence of Electron Viscosity in Superballistic GaAs Point Contacts
Daniil I. Sarypov, Dmitriy A. Pokhabov, Arthur G. Pogosov +4
Electron transport in suspended and non-suspended GaAs point contacts (PCs) of different widths is experimentally studied. The superballistic contribution to the conductance, that…
Piezoelectric electromechanical coupling in nanomechanical resonators with two-dimensional electron gas
A. A. Shevyrin, A. G. Pogosov, A. K. Bakarov +1
The electrical response of two-dimensional electron gas to vibrations of a nanomechanical cantilever containing it is studied. Vibrations of perpendicularly oriented cantilevers ar…
The Coulomb Blockade Resonant Breakdown Caused By The Quantum Dot Mechanical Oscillations
A. G. Pogosov, M. V. Budantsev, A. A. Shevyrin +3
Influence of forced mechanical vibrations of a suspended single-electron transistor on electron tunneling through the quantum dot limited by the Coulomb blockade is investigated. I…
