We investigate the temperature dependence of the linear response of a generic Fermi liquid to a pair-creating perturbation, referred to as precursory Cooper flow. We show that the form of this dependence allows for an unbiased prediction of the BCS transition temperature, $T_c$, from data collected at temperatures dramatically higher than $T_c$. We employ this technique to calculate the phase diagram of superconducting states with multiple orbital channels in a moderately interacting two-dimensional uniform electron gas. Our analysis of the leading correction to the pair susceptibility reveals the possibility of predicting the temperature evolution of pairing correlations and $T_c$ in low-temperature superconductors through the analysis of DC $I$-$V$ characteristics of tunnel junctions at high temperatures. |
