Researchers have made a breakthrough in understanding the behavior of extensive $U(1)$ charges after a quantum quench, a phenomenon where a system's parameters are suddenly changed. By utilizing space-time duality, they characterized the $n$-time cumulant generating function, also known as $n$-Full Counting Statistics ($n$-FCS), for initial states symmetric under the charge's action1. The study reveals that when temporal correlations are weak, the transport properties of the system can be effectively described. This advancement sheds light on the complex dynamics of quantum systems, particularly in the context of quantum quenches. The findings have significant implications for the field of quantum physics, as they provide a deeper understanding of the behavior of quantum systems under sudden changes. So what matters to practitioners is that this research offers a new framework for analyzing the dynamics of quantum systems, enabling more accurate predictions and control over their behavior.
