Welcome to SPEC!
We are the Condensed Matter Physics laboratory of IRAMIS (Saclay Institute for Radiation and Matter), a part of the French National Atomic Energy Commission (CEA: Commissariat à l'Energie Atomique) in Saclay, France.
SPEC is also "Unité de Recherche Associée" with the CNRS : URA CNRS 2464.
At SPEC, we strive to be at the forefront of fundamental Condensed Matter Physics Research. Our research interests encompass a wide variety of subject matters ranging from nano-to macro-scopic scales and from the most fundamental aspects of science to applications, patents and technology transfer.
Director: François Daviaud
Deputy Director: Patrice roche

In a vortex-state magnetic nanodisk, the static magnetization is curling in the plane, except in the disk center where it is pointing out-of-plane, either up (polarity p=+1) or down (p=-1). The lowest energy excitation mode of this ground state is the so-called gyrotropic mode [1], corresponding ... More » |

If it truly does exist, a "supersolid" would represent a new state of matter that combines mechanical rigidity and superfluid properties. This would be a new phase of condensed matter, but whether such a state has indeed been discovered and how it can be reached is still far from clear. As reported ... More » |
