It presents a new method leveraging Zeeman coherence oscillations to slow light, distinct from EIT-based approaches, and demonstrates dark polariton propagation in the medium.

Findings

Effective light slowing via Zeeman coherence oscillations

No trapping states required for the method

Propagation of dark polaritons demonstrated

Abstract

We present the theory of a new method to slow a linearly polarized probe pulse as it propagates through a duplicated two-level system driven by an orthogonally polarized control field. The method makes use of Zeeman coherence oscillations (CZO) that arise in the atomic system because of the spatial and temporal modulation of the total polarization. This method exhibits properties similar to those that rely on the electromagnetically induced transparency (EIT) but without the existence of any trapping state. We demonstrated also the propagation of a dark polariton in the medium
