Experimental Study of Low Dimensional Bose Gases

Trapped ultracold atoms are one of the primary platforms enabling the development of quantum computation and simulation. Continued scaling towards large, robust quantum mechanical systems relies on our ability to exert increasing levels of control over these atomic systems. The team working on the Rubidium-87 experiment at Collège de France have demonstrated unprecedented precision manipulation of low-dimensional ultracold atoms, the density and spin spatial profiles of which they are able to arbitrarily set via the usage of digital micromirror devices in a high resolution imaging setup. A remaining obstacle in the path towards total control over this system is in the lack of tunability of the interaction strength between the individual atoms. To that end, the goal of this project is to experimentally implement a protocol for modulating the interatomic interactions between ultracold alkali atoms in a system which is already able to exert state-of-the-art control over all other properties of the atomic gas. This will enable the team to explore the strongly-interacting regime for low-dimensional gases, while the intern will develop skills unique to the team at Collège de France which may be implemented on the Rubidium-87 apparatus at the University of Toronto.
