Uni-dimensional Quantum dynamics in Ring trapS – UniQ-RingS

Atomtronics is an emerging quantum technology which uses tailored potentials for atomic matter waves with applications that range from quantum simulations to the development of practical devices. The goal of UniQ-Rings is to investigate experimentally for the first time fundamental questions relevant to atomtronics: the complex dynamics of 1D superfluid currents in near- and far-from-equilibrium situations, exotic dynamics of nonlinear atomic waves, and explore the uncharted territory of strongly-interacting regime in the 1D ring geometry. UniQ-Rings will address these problems using two complementary atomic Bose-Einstein condensate experiments. Building upon their own specific features, the platforms will develop 1D ring structures to trap atoms, with the goal of studying 1D superfluidity in two extreme interaction parameter regimes, and approach the middle region where theoretical predictions are currently unavailable. The UniQ-Rings project will benefit from high-quality support of established theoreticians, expert in theoretical and numerical methods for 1D quantum systems in different regimes, which will bring pivotal contribution for the success of the project. Experiments will validate the analytical predictions, and guide future theoretical direction beyond the current state-of-the-art.
