It applies an ab initio anisotropic Migdal-Eliashberg approach to elucidate the pairing mechanism and gap structure in Li-decorated monolayer graphene, aligning theoretical predictions with experimental data.

## Key findings

- Superconductivity in Li-decorated graphene is phonon-mediated.
- Predicted Tc range matches experimental observations.
- Superconducting gap is anisotropic and single in nature.

## Abstract

The ab initio anisotropic Migdal-Eliashberg formalism has been used to examine the pairing mechanism and the nature of the superconducting gap in the recently discovered lithium-decorated monolayer graphene superconductor. Our results provide evidence that the superconducting transition in Li-decorated monolayer graphene can be explained within a standard phonon-mediated mechanism. We predict a single anisotropic superconducting gap and a critical temperature Tc = 5.1-7.6 K, in very good agreement with the experimental results.
