Abstract: | We describe an experimental system that integrates the techniques for producing ultracold
atomic gases with the techniques for cooling solid bodies to cryogenic temperatures.
Ultracold clouds of 87Rb are prepared in a trap setup based on room-temperature
coils and subsequently transported to a superconducting microstructure by means of optical
tweezers. The superconducting microstructure generates a magnetic microtrap and is cooled
by a helium-flow cryostat that can achieve temperatures down to 2 K. Both the
room-temperature trap setup and the superconducting microtrap are installed in the same
ultra-high-vacuum chamber. The presented system is well suited to create hybrid quantum
systems by combining ultracold atomic gases and superconducting devices. |
