Harnessing quantum many-body phenomena with long-range interacting AMO platforms
Abstract
In quantum mechanics, an ensemble of particles can develop into a complex correlated state under the effect of interactions. However, most of such many-body states do not provide useful quantum resources that are accessible to current devices. Hence, a particularly intriguing question crucial for advancing quantum technologies is how to harness interaction effects to create quantum many-body states with significant advantage over classical systems in a controllable manner, especially with the tools available in present laboratories. This project focuses on the class of quantum states that can be used for improving the precision of measurements and the performance of sensors, which have a wide spectrum of applications ranging from navigation systems to environmental monitoring. In particular, the project exploits the capabilities offered by arrays of ultracold dipolar particles to design practical protocols for generating useful many-body states. It aims to theoretically unravel the connections between symmetries, thermalization, and sensing capabilities, leveraging analytical and numerical investigations for systems with large spin sizes. The outcome of this project will improve the understanding of nonequilibrium many-body phenomena and quantum correlations, as well as provide guidance for engineering correlated quantum states in real systems. Accordingly, this project has broad impacts on AMO physics, condensed matter physics, quantum sensing and metrology.
