Fig. 2: Reciprocal and nonreciprocal transmission behaviors in a two-level giant-atom system.
From: Nonreciprocal and chiral single-photon scattering for giant atoms
Transmission rates T1→2 and T2→1 versus the detuning Δ and the phase difference θ. a and b with the atomic dissipation rate γe = 0; c and d with γe/Γ = 10, where Γ is the atomic emission rate into the waveguide. Other parameters: accumulated phase ϕ0 = π/2 and photon propagation time τΓ = 0.01.
