Service de physique de l'état condensé

Research unit


The Condensed Matter Physics Laboratory (SPEC) is a CEA-CNRS mixed unit (UMR 3680) which is part of the DRF/IRAMIS of CEA Saclay and INP at CNRS.
The physic of condensed matter is one of the biggest research themes conducted at SPEC, from its fundamental aspects to its various applications. The research includes a variety of subjects on complex systems and statistical physics, nanophotonic, nanoelectronic, nanomagnetism and oxydes, quantronics and quantum technologies. Theoretical and experimental approaches at SPEC are diverse and allows a wide range of scientific research at the nano-scale to macroscopic objects. Many activities of this laboratory benefit from many platforms: cryogenic, UBM (for ultra-bas bruit magnétique or very low magnetic noise), mecanical and nanofabrication workshop...
Having multiple scientific publications, SPEC is also a meeting point for technological and patent transfer. The laboratory is part of many collaborations at the national level (CNRS, CEA, Paris-Saclay university...) as well as at the international level.
