Scalability of non-adiabatic effects in lithium-decorated graphene superconductor

Abstract The analysis is conducted to unveil how the non-adiabatic effects scale within the superconducting phase of lithium-decorated graphene . Based on the Eliashberg formalism it is shown that the non-adiabatic effects notably reduce essential superconducting parameters in and arise as a significant oppressor of the discussed phase. Moreover, non-adiabaticity is found to scale with the strength of superconductivity, proportionally to the phonon energy scale and inversely with respect to the electron-phonon coupling. These findings are partially in contrast to other theoretical studies and show that superconductivity in is more peculiar than previously anticipated. In this context, the guidelines for enhancing superconducting phase in and sibling materials are also proposed.
