A novel atomic quantum simulator may bring theoretical predictions to life
Since the discovery of superconductivity in 1911, pioneering theoretical and experimental work has opened a window on the non-classical rules governing the quantum world. As with that early discovery, many phenomena result from the collective behaviour of systems of many subatomic components (many-body systems) exhibiting macroscopic quantum effects. The collective behaviour of groups of two or more 'bodies' can be quite different from those of individual particles, and the underlying interactions can occur at (relatively) large distances. This is often true of the so-called fermionic many-body systems, and ultracold atomic quantum gases offer a unique opportunity for quantum simulation of such systems. The EU-funded CriLiN project is developing a novel atomic quantum simulator that could enable the experimental demonstration of important theoretical descriptions for the first time.
