Proposal for Spin-Synchronization in Cold Rubidium Vapor

POSTER

Abstract

Synchronization of coherently driven quantum mechanical spin systems is investigated theoretically. Starting from a microscopic framework that accounts for several auxiliary states in the rubidium-87 hyperfine state manifolds, an effective master equation for the spin-1 system is derived. Several level schemes and protocols for observing synchronization are benchmarked. Focusing on the so-called synchronization blockade [1], various synchronization measures are discussed and contrasted. To model an experimental protocol for the read-out of the coherences, which govern a subset of the synchronization measures, the propagation of read-out beams through a non-interacting atomic vapor is simulated by self-consistently solving the full atomic master equation and Maxwell's equations.
