This $285,164 project grant, awarded by the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program, will fund a series of experiments by the research group at The Pennsylvania State University to study the behavior of ultra-cold 87Rb atoms confined in one-dimensional optical lattices. The project aims to explore the transition from nearly integrable to non-integrable many-body quantum systems, with the goal of developing a universal framework for understanding the dynamics of closed, interacting quantum systems. Key measurements will include momentum distributions and quasiparticle rapidities of the 1D lattice-gas systems, both in and out of equilibrium. The results could provide insights relevant to quantum computing, quantum sensing, and other quantum technologies that rely on particle interactions. The award will also support the training of graduate and undergraduate students in cutting-edge experimental physics and quantum science.
