Many systems are known to undergo Bose-Einstein condensation at low temperatures such as ultracold atomic gases, superconductors and liquid helium. In these systems, a macroscopic number of atoms occupy the same single-particle state, thereby amplifying quantum-mechanical microscopic properties to a macroscopic level. These quantum condensates are important not only from a fundamental physics point of view but also for applications to quantum information and quantum simulators. The quantum condensate research team aims to promote these researches theoretically and experimentally.
