Abstract
In this talk, I will elaborate on our recent experimental advancements in probing many-body correlations through non-equilibrium dynamics. By making use of a loss channel, we observe a universal dissipative dynamic in one-dimensional strongly-correlated quantum gases. This universal dynamic furnishes us with information regarding the anomalous dimension of the system, which is arduous to measure by conventional means. Through non-adiabatic ramping, we are able to probe the critical regions that lack a well-defined quasi-particle description. Based on non-adiabatic ramping, we have developed an integrable formula to depict the measured observables, and the results go beyond the conventional account of the Kibble-Zurek mechanism. These methods significantly enrich the approaches to measuring a quantum system and can be further extended to diverse systems for extracting different types of many-body correlations.
