Observation of the scaling dimension of fractional quantum Hall anyons

A. Veillon, C. Piquard, P. Glidic, Yosuke Sato et autres

Abstract Unconventional quasiparticles emerging in the fractional quantum Hall regime1,2 present the challenge of observing their exotic properties unambiguously. Although the fractional charge of quasiparticles has been demonstrated for nearly three decades3–5, the first convincing evidence of their anyonic quantum statistics has …

Signature of anyonic statistics in the integer quantum Hall regime

P. Glidic, Ivana Petković, C. Piquard, A. Aassime et autres

Anyons are exotic low-dimensional quasiparticles whose unconventional quantum statistics extends the binary particle division into fermions and bosons. The fractional quantum Hall regime provides a natural host, with first convincing anyon signatures recently observed through interferometry and cross-correlations of colliding beams. However, …

Cross-Correlation Investigation of Anyon Statistics in the $\nu=1/3$ and $2/5$ Fractional Quantum Hall States

P. Glidic, Olivier Maillet, A. Aassime, C. Piquard et autres

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 dual-source - analyzer quantum point contact setup, also referred to as 'collider', the anyon exchange phase of fractional …

Elaboration and characterization of porous ultrathin gold films grown by ion beam assisted deposition

A. Aassime, Marc Duquennoy, Frédéric Hamouda, Tahar Kadi et autres

The growth of ultrathin gold layers on a silicon substrate is performed with an unconventional ion beam assisted deposition. In this setup, evaporated gold flow and ion beam flux are perpendicular. 5 and 10 nm thick gold were deposited on tilted samples …

Revisiting the Role of Metallic Antennas to Control Light Emission by Lead Salt Nanocrystal Assemblies

Hongyue Wang, A. Aassime, Xavier Le Roux, Nick J. Schilder et autres

Metallic antennas have become ubiquitous tools for extracting light from atoms, molecules, and nanocrystals. Their design is generally based on the understanding that such antennas operate through the Purcell effect: the dependence of the fluorescence rate of individual emitters on their environment. …

Germanium microlasers on metallic pedestals

Ayman S El-Baz, M. El Kurdi, A. Aassime, S. Sauvage et autres

Strain engineering is a powerful approach in micro- and optoelectronics to enhance carrier mobility, tune the bandgap of heterostructures, or break lattice symmetry for nonlinear optics. The dielectric stressors and bonding interfaces used for strain engineering in photonics can however limit thermal …

Electroluminescence of Colloidal Quantum Dots: Electroluminescence of Colloidal Quantum Dots in Electrical Contact with Metallic Nanoparticles (Advanced Optical Materials 2/2018)

Hongyue Wang, Quynh Le‐Van, A. Aassime, Xavier Le Roux et autres

In article number 1700658, Hongyue Wang and co-workers show that the electroluminescence of colloidal quantum dots exhibits unexpected and technology-enabling properties when the emitters are brought in electrical contact with metallic nanoparticles. The hybridization between the two species is robust to quenching, …
