A Joint Theory-Experiment Investigation of Steady-State Synchronization in Effective Spin-1 System

POSTER

Abstract

Understanding and characterizing the steady-state synchronization in dissipative quantum systems induced by external driving fields is vital for the advancement of quantum technologies. This work presents a joint theoretical and experimental study of steady-state synchronization of an effective spin-1 system, realized using $^{87}$Rb atoms loaded into a magneto-optical trap. Control and probe fields that address the D2 transition realize both effective coherent coupling and effective dissipative pathways in the F=1 hyperfine ground states [1]. Additional dissipative processes are realized by coupling to the D1 line. To extract the steady-state synchronization encoded in the atomic coherences, we apply a retrieval pulse after a variable hold time and analyze the retrieved signal [2,3]. Building on Ref. [2], we use a polariton picture-based protocol to extract the drive-induced steady-state synchronization. The protocol is validatedthrough numerical simulations by self-consistently solving a set of coupled Maxwell–Bloch equations, which account for the interplay between the atomic and field degrees of freedom. Comparisons between theory and experiment are presented.
