Quantum state engineering in arrays of nonlinear waveguides

Abstract In the current quest for efficient and experimentally feasible platforms for implementation of multimode squeezing and entanglement in the continuous variable regime, we underpin and complement our results on the generation of versatile multimode …

Effect of sintering germanium epilayers on dislocation dynamics: From theory to experimental observation

Abstract High-quality germanium epilayers on Si with low threading-dislocation density were achieved by sintering of porous Ge/Si films. The process consists in the formation of porous Ge nanostructures by …

Entropy reduces the lifetime of magnetic bits

Retaining stored information in magnetic materials relies on making energy barriers difficult to overcome. In a theoretical study, two researchers at C2N show that the resulting entropy can have the opposite effect. Their results challenge …

Scientists use photons as threads to weave novel forms of matter

Positive and negative electric charges attract each other, forming atoms, molecules, and all that we usually refer as matter. Negative charges instead repel each other, and in order to form atom-like bound objects some extra glue is needed, in …
