a Free energy landscape for the IVC phase transition in RTG as a function of displacement field. A metastable regime is visible, where a free energy barrier separates an ordered minimum from the normal state. The fixed density is indicated. Inset: horizontal cut corresponding to the dashed black line in the main panel. The left and right circles are schematics of the Fermi surface in the normal and IVC phases, respectively. b The decay threshold energy in the vicinity of the transition (blue). The dashed purple line corresponds to the result in the absence of the superconductor. Inset: comparison of the surface tension contributions from the superconducting and IVC phases. The parameters used: T = 30 mK UC =  1.46 eV nm2, gatt. = 0.21 eV nm2, ω* = 0.5 meV.
