Probing quantum phases in ultra-high-mobility two-dimensional electron systems using surface acoustic waves
Mengmeng Wu, Xiao Liu, Renfei Wang +6
Transport measurement, which applies an electric field and studies the migration of charged particles, i.e. the current, is the most widely used technique in condensed matter studi…
Suppression of Spin Pumping at Metal Interfaces
Youngmin Lim, Bhuwan Nepal, David A. Smith +15
An electrically conductive metal typically transmits or absorbs a spin current. Here, we report on evidence that interfacing two metal thin films can suppress spin transmission and…
Fractional focusing peaks and collective dynamics in two-dimensional Fermi liquids
Adbhut Gupta, Gitansh Kataria, Mani Chandra +6
Carrier transport in materials is often diffusive due to momentum-relaxing scattering with phonons and defects. Suppression of momentum-relaxing scattering can lead to the ballisti…
Dynamic Response of Wigner Crystals
Lili Zhao, Wenlu Lin, Yoon Jang Chung +4
The Wigner crystal, an ordered array of electrons, is one of the very first proposed many-body phases stabilized by the electron-electron interaction. This electron solid phase has…
Hydrodynamic and ballistic transport over large length scales in GaAs/AlGaAs
Adbhut Gupta, J. J. Heremans, Gitansh Kataria +4
We study hydrodynamic and ballistic transport regimes through nonlocal resistance measurements and high-resolution kinetic simulations in a mesoscopic structure on a high-mobility…
Precision measurement of electron-electron scattering in GaAs/AlGaAs using transverse magnetic focusing
Adbhut Gupta, Jean J. Heremans, Gitansh Kataria +4
Electron-electron (e-e) interactions assume a cardinal role in solid-state physics. Quantifying the e-e scattering length is hence critical. In this paper we show that the mesoscop…
