Missions
In the context of the development of ground-based gravitational wave detectors, we are recruiting a researcher for a 24-month contract to work on the preparation of improvements to Virgo, Virgo_nEXT and the Einstein Telescope(ET).
In particular, the candidate will focus on carrying out an experiment to develop a squeezing source funded by the ANR (Agence Nationale de la Recherche) in the Virgo optics laboratory at the APC.
Squeezing is a key technology for reducing quantum noise, one of the main limitations on the sensitivity of current and future detectors. This noise, caused by fluctuations in the vacuum entering the detector, can be reduced by replacing the vacuum with a squeezed vacuum. The use of squeezed states has already led to a remarkable increase in the sensitivity of the Virgo and LIGO detectors.
Activités
The successful candidate will collaborate with the experimental team of the Virgo/ET group at the APC and will be particularly responsible for contributing to the experimental activities on the realisation of a frequency-dependent squeezing source for quantum noise reduction, underway in the APC clean room. He/she will contribute to both the design of the experiment and its implementation in the APC's optical laboratory.
Compétences
The candidate must have a good knowledge of the basis of gravitational waves and the principle of measurement with interferometric detectors. He/she should have solid skills in optics, both in terms of optical system design and experimental activity.
Basic knowledge of quantum optics would also be appreciated.
Contexte de travail
The APC laboratory, located in the centre of Paris (France), on the Université Paris Cité campus, is a multidisciplinary laboratory developing research in five scientific fields: cosmology, high-energy astrophysics, gravitation, particle physics and theory. The candidate will join the Gravitation group, which has been involved in the development of detectors for gravitational astronomy for over a decade. The successful candidate will join the Virgo/ET team, which consists of around ten senior and junior researchers and PhD students.
