    • The upper bound marks the crossover length where finite spatial-size corrections to the thermodynamic behavior occur. To get a sense for this scale we note that LCO =ξ Nas Δ0 /T, where Δ0 is the BCS gap and Nas is the number of transverse channels.

    • The fugacity of quantum phase slips is ζ∼ e-2c RQ / Rξ, with ca π 163 (Ref.). By requiring that ζ is not inhibitively small, we obtain Rξ >c RQ. For Rtot ∼ RQ, the length must be in the range L∼ RQ ξ/ Rξ <ξ/c.
