    Abstract

    We theoretically study the impact of magnetic sublevels on superradiance lattices (SLs) in room temperature Rb87 vapor. By incorporating the full Zeeman manifold into the master-equation framework, we demonstrate that the presence of magnetic sublevels significantly modifies the velocity-scanning tomography spectra of SLs. Our simulations reveal that two specific optical configurations exhibit clear lattice features while being robust against collision effects, making them favorable for experimental realization. Furthermore, we explore the influence of an external magnetic field, which lifts the degeneracy of Zeeman sublevels and enables multiple distinguishable SLs. These findings not only clarify the discrepancies between simplified SL models and experimental observations, but also pave the way for constructing spin-dependent SLs.
