Abstract:
Bose-Einstein condensates (BECs) are macroscopic coherent matter waves that have revolutionized quantum science and atomic physics. However, despite long running experimental efforts, continuous amplification of an atomic matter wave, preserving its phase coherence has remained an open challenge. Creating a continuous source of matter wave gain is key to realizing a continuous-wave (CW) BEC and by continuously extracting atoms to forming a continuous-wave atom laser. In this talk I will report our demonstration of continuous Bose-Einstein condensation by creating a continuous-wave (CW) condensate of strontium atoms that lasts indefinitely. It is a matter-wave equivalent of a CW optical laser with fully reflective cavity mirrors. This advance overcomes a fundamental limitation of all atomic quantum gas experiments to date: the need to execute several cooling stages time-sequentially. Continuous matter-wave amplification will make possible CW atom lasers, atomic counterparts of CW optical lasers that have become ubiquitous in technology and society.
