Time evolution of the entangling power of the atom-atom state after BSM (
PF−=|Ψ−〉FF〈Ψ−|
) as a function of scaled time τ for strong coupling regime, i.e., R = 10 with β = 0 (solid blue line), β = 10 × 10−9 (dashed red line) and β = 15 × 10−9 (dot-dashed green line). We have set ω0/λ = 1.5 × 109. |
