Abstract

We study the dynamics of light interacting with a near-resonant atomic medium using the truncated Wigner and positive P phase-space representations. By mapping the atomic degrees of freedom via the Jordan-Schwinger transformation, we first analyze the system under unitary evolution before extending the treatment to include an optical reservoir. While both methods capture the main features of the light-matter dynamics, our results demonstrate that the truncated Wigner approximation deviates significantly at higher interaction strengths and in regimes where reservoir-induced noise is prominent.
