Cold atoms and matter waves is a research area focused on the quantum behavior of dilute atomic gases cooled to microkelvin or nanokelvin temperatures, where their de Broglie wavelengths become comparable to interparticle spacing and wave-like properties dominate. It encompasses the production and manipulation of Bose–Einstein condensates and degenerate Fermi gases, coherent control of atomic matter waves using optical and magnetic potentials, and exploration of many-body quantum phenomena in engineered lattices and traps. The field underpins precision metrology, quantum simulation, and interferometry by exploiting long coherence times, tunable interactions, and highly controllable external degrees of freedom of ultracold atomic ensembles.
Researchers from the Institute for Molecular Science have revealed quantum entanglement between electronic and motional states in their ultrafast quantum simulator, generated by the repulsive force due to the strong interaction ...
