LPENS-Paris (CNRS) – The Laboratoire de Physique de l’Ecole Normale Supérieure (LPENS), created in 2019, is an interdisciplinary fundamental research laboratory in physics and its interfaces.
The laboratory’s scientific activities cover a vast exploratory field in fundamental or applied physics, experimental or theoretical, and are organised into six axes: Astrophysics, Cosmology and Gravitation, Biophysics, Fluids and Interfaces, Fundamental Interactions, Quantum Materials and Devices, Statistical Physics.
Key people on the project
Gwendal FEVE, PI at LPENS, is a University Professor at Sorbonne Université in Paris. He received his PhD from Université Pierre et Marie Curie in 2006 on the development of triggered single electron emitters in condensed matter. After working one year at C2N (Palaiseau), he joined LPENS in 2008 for developing electron quantum optics experiments based on the emission and control of single electron excitations in ballistic quantum conductors.
In particular, he developed experimental techniques based on two-particle interferometry, where the measurement of the fluctuations of the electrical current at the output of an electronic beam-splitter is used for the characterization of the quantum phase coherence of the input electron beams.
Recently, he moved to the application of these techniques for investigating anyons, the excitations of fractional quantum Hall conductors. In particular he experimentally demonstrated in 2020 the fractional statistics of anyons by studying anyon collisions at a beam-splitter.
