## Networks

Our group has initiated the **CASIMIR NETWORK **which animated the international community in the domain for several years. Astrid Lambrecht has initiated the proposal of the ESF network *New Trends and Applications of the Casimir Effect. *She has then chaired the network from 2008 to 2010. Serge Reynaud has been member of the executive board of the Steering Committee from 2010 to 2014.

Our group had also initiated the **GREX Network (Gravitation and Experiment)** which was a CNRS Groupe de Recherche chaired by Serge Reynaud from 1995 to 2006. This group then led to the birth of the **GRAM Action (Gravitation, Références, Astronomie, Métrologie)**, which becomes in 2016 a Programme National of **INSU-CNRS** and **INP-CNRS**. Serge Reynaud has been a member of the Scientific Board of the GRAM since its creation in 2010.

These 2 networks have organized of a large number of conferences.

Our group is also part of the **GDR IQFA (Quantum Information, Foundations & Applications)** and of the **DIM IFRAF (Institut Francilien de Recherche sur les Atomes Froids)**.

## Collaborations

Our group is part of the collaborations

**MICROSCOPE, test of the equivalence principle in space**

**GBAR, measurement of the free fall of antihydrogen atoms at CERN**

**MIGA, matter wave – laser interferometry gravitation antenna
**

Our group works in collaboration with a number of experimental or theoretical groups, as well as in the frame of space projects.
