Enhanced shot noise in graphene quantum point contacts with electrostatic reconstruction
M. Garg, O. Maillet, N. L. Samuelson +13
Shot noise measurements in quantum point contacts are a powerful tool to investigate charge transport in the integer and fractional quantum Hall regime, in particular to unveil the…
Quasiparticle Andreev scattering in the fractional quantum Hall regime
P. Glidic, O. Maillet, C. Piquard +6
The scattering of exotic quasiparticles may follow different rules than electrons. In the fractional quantum Hall regime, a quantum point contact (QPC) provides a source of quasipa…
On-chip thermometry for microwave optomechanics implemented in a nuclear demagnetization cryostat
X. Zhou, D. Cattiaux, R. R. Gazizulin +7
We report on microwave optomechanics measurements performed on a nuclear adiabatic demagnetization cryostat, whose temperature is determined by accurate thermometry from below 500$…
Probing superfluid with high-frequency nanomechanical resonators down to temperatures
A. M. Guenault, A. Guthrie, R. P. Haley +10
Superfluids, such as superfluid and , exhibit a broad range of quantum phenomena and excitations which are unique to these systems. Nanoscale mechani…
Surface-induced near-field scaling in the Knudsen layer of a rarefied gas
R. R. Gazizulin, O. Maillet, X. Zhou +3
We report on experiments performed within the Knudsen boundary layer of a low-pressure gas. The non-invasive probe we use is a suspended nano-electro-mechanical string (NEMS), whic…
Detecting the "phonon wind" in superfluid by a nanomechanical resonator
A. M. Guenault, A. Guthrie, R. P. Haley +8
Nanoscale mechanical resonators are widely utilized to provide high sensitivity force detectors. Here we demonstrate that such high quality factor resonators immersed in superfluid…
Slippage and boundary layer probed in an almost-ideal gas by a nano-mechanical oscillator
M. Defoort, K. J. Lulla, T. Crozes +3
We have measured the interaction between He gas at 4.2K and a high-quality nano-electro-mechanical string device for its first 3 symmetric modes (resonating at 2.2MHz, 6.…
Cross-Correlation Investigation of Anyon Statistics in the and Fractional Quantum Hall States
P. Glidic, O. Maillet, A. Aassime +6
Recent pioneering works have set the stage for exploring anyon braiding statistics from negative current cross-correlations along two intersecting quasiparticle beams. In such a du…
Driving nanomechanical resonators by phonon flux in superfluid \(\mathbf{^4He}\)
A. M. Guénault, A. Guthrie, R. P. Haley +10
We report on nanomechanical resonators with very high-quality factors operated as mechanical probes in liquid helium \(^4\mathrm{He}\), with special attention to the superfluid reg…
