The Cold Atoms Lab (CAL) is a compact, atom chip-based facility for examining ultra-cold quantum gases such as Bose-Einstein condensates (BEC). CAL represents a new era in ISS research, as now, for ...

In a cold gas, the atomic velocity distribution shrinks and the quantum uncertainty in knowing the positions of the particles grows. This uncertainty defines the size λ of regions of space ...

The cold-atom approach involves using finely focused laser beams (the ‘optical tweezers’) to trap individual atoms in a two-dimensional grid held at temperatures close to absolute zero.
