Common behavior of the scaled condensation energy for both high-$T_c$ and conventional superconductors

V. R. Shaginyan, A. Z. Msezane, S. A. Artamonov

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(…
