Loop formation time. (A) Normalized loop formation time versus tension for parallel configuration of operators (θ = 180°, Eqs. 4, 18, and 19). The legend indicates loop sizes. The normalized loop formation time is defined so that it is unity when tension is zero. In this way, the specific effects of tension are isolated. (B) Normalized loop formation time versus tension for hairpin looping configuration (θ = 0°).
