报告摘要： Anyons emerge as elementary excitations in low-dimensional quantum systems and exhibit behavior distinct from bosons or fermions. This talk will present the study of emergent anyonic correlations in a one-dimensional strongly interacting quantum gas, resulting from the phenomenon of spin-charge separation [1]. A mobiles impurity provides the necessary spin degree of freedom to engineer anyonic correlations and simultaneously acts as a probe to reveal these correlations. Starting with bosons, the statistical phase is tuned to transmute bosons through anyons to fermions, leading to an asymmetric momentum distribution. As a novel framework, we propose an effective “swap” model to capture the anyonization mechanism at the microscopic level [2]. By assigning a complex phase factor to the swapping processes, we demonstrate the anyonic characteristics through the one-body correlator of the impurity. Going beyond equilibrium conditions, we further explore the dynamical properties of the anyonic correlations. Our work provides new avenues for engineering many-body anyonic behavior in quantum simulation platforms.
