This project aims to determine the mass and geometric phase of topological vortex excitations in a superfluid gas of atoms. Topological excitations in quantum systems behave as particles, and determining their mass and geometric phase is essential for understanding their dynamics. Understanding the dynamics of topological excitations is critical for developing future quantum technologies. The intended outcome is to open a pathway for experimental observations that may solve the long standing vortex mass problem in superfluids. The fundamental knowledge generated by this project could be useful for developing technologies based on topological quantum systems.
