Universal condensation energy scaling for both conventional and high
$T_c$ superconductors
We analyze the scaling of the condensation energy $E_{\Delta}$ divided by $\gamma$, $E_{\Delta}/\gamma\simeq N(0)\Delta_1^2/\gamma$, of both conventional superconductors and unconventional high-$T_c$ one, where $N(0)$ is the density of states, $\Delta_1$ is the maximum value of the superconducting gap and $\gamma$ is the Sommerfeld coefficient. For the first time, we show …
