Anomalous high-density spin noise in a strongly interacting atomic vapor

Spin noise spectroscopy (SNS) has become a mainstream approach to probe the dynamics of a spin ensemble in and out of equilibrium. Current models describing spin noise in interacting samples are based on an effective single-particle dynamics in a…

Vapor Deposition of Hybrid Halide Perovskites in Ultra-High Vacuum: Challenges Revealed by Probing the Organization Dynamics in Real Time

With record efficiencies and reduced costs, hybrid halide perovskite solar cells could revolutionize photovoltaics, provided that the crippling instability problem is resolved. To reveal the relationship between structural defects and instability,…

Photodynamic Therapy Using Pulsed-Laser Irradiation of Gold Nanoparticles for the Treatment of Cancers with High Basal Oxidative Stress

For over 20 years, considerable research has been carried out on the use of nanotechnologies in cancer treatment. Beyond the photothermal effect of irradiating gold nanoparticles, the photodynamic effect with reactive oxygen species (ROS) production…

Probing interactions by spin noise spectroscopy

Dans les systèmes magnétiques, la spectroscopie du bruit fondamental dû aux fluctuations aléatoires du spin, appelée spectroscopie du bruit de spin (SNS), est réalisée optiquement en mesurant les fluctuations de la rotation de Faraday subie par un…

Wavefront shaping enhanced nano-optomechanics down to the quantum precision limit

We introduce wavefront shaping as a tool for optimizing the sensitivity in nano-optomechanical measurement schemes. We perform multimode output analysis of an optomechanical system consisting of a focused laser beam coupled to the transverse motion…

Single Graphene Quantum Dots in a molecular crystal

Les boîtes quantiques de graphène (abrégé GQD en anglais) sont des objets nanométriques composés de centaines d'atomes de carbone. Ces nouveaux émetteurs quantiques fonctionnent dans le visible et sont très prometteurs pour des applications en…

Optimal Control of Levitated Nanoparticles through Finite-Stiffness Confinement

Optimal control of levitated nanoparticles subjected to thermal fluctuations is a challenging problem, both theoretically and experimentally. In this Letter, we compute the time-dependent harmonic confining potential that steers, in a prescribed…
