Comment on “Stabilized Pair Density Wave via Nanoscale Confinement of Superfluid ${}^3\mathrm{He}$”

Figure 1

Transport anomalies attributed by Shook et al. to a PDW in the $0.6\mu \mathrm{m}$ resonator [1]. (a) Channels and basin of the resonator of different thickness superimposed with the model of velocity field [1, Supplemental Material]. Both the channels and the basin contribute to the resonator response. (b) The phase diagram reported by Shook et al. [ [1], Fig. 4(d)] with the Ginzburg–Landau calculation of the $A\text{−}B$ boundary (GL) rescaled to the basin thickness [3]. The upper and lower anomalies, open and filled green circles, are consistent with signatures of the same phase transition in channels and basin. The bulk superfluid transition $T_c^{\mathrm{bulk}}$ is shown for reference.
