Magnetism of fine particles of Kondo lattices, obtained by high-energy ball-milling
The study of WL flares have been rendered very difficult by their short duration and very low contrast which makes their observations from Earth rare and of poor quality.

In this context, solid state materials such as rare-earth ion doped crystals (REIC) offer a prime alternative to atomic vapors since they combine the absence of motion with long coherence lifetime and large inhomogeneous width.
Revival of Silenced Echo and Quantum Memory for Light
Our results highlight the potential of rare-earth-ions doped crystals for entangled quantum nodes and bring quantum networks based on solid-state resources one step closer.
