(a),(b) Evolution traces of 
at different θΣ with/without the presence of decoherence. (a) depicts the traces in the dissipationless situation κ/2π = 0 and (b) corresponds to κ/2π = 150 kHz. The panels 1–6 in (a) and (b) correspond to θΣ = π/6, π/4, π/3, 5π/12, 17π/36 and π/2, respectively. (c) Chiral area S versus θΣ in the presence of decoherence. The total time T is set as T = 1 μs and the solid, dotted, dot-dashed and dashed lines correspond to the situations with decay rates κ/2π = 0, 100, 200 and 500 kHz, respectively.
