Description
In this Erbium-Lithium mixture experiment, we want to realize a quantum gas mixture of erbium and lithium. Remarkably for this mixture is the heavy mass imbalance with a factor of 28, where thermalisation properties will be interesting to observe.
As an additional constrain, we want to trap erbium in a shallow trap at 1064 nm, whereas lithium shall be in a narrow trap at 841 nm, where a tuneout wavelength of erbium is expected.
Besides this thermalisation aspect, the combination of erbium and lithium enables polaron physics, with heavy dopants of erbium in an lithium environment.
Currently, we have loaded erbium and lithium in a dipole trap, whereas the measurement of the tuneout wavelength and the transport of both species into a glass cell are ungoing.
