# Superconductivity in the presence of strong electron-phonon interactions and frustrated charge order

## TL;DR

This paper investigates how strong electron-phonon interactions can promote superconductivity in frustrated lattice systems, using sign-problem-free Quantum Monte Carlo simulations to reveal that frustration enhances superconducting tendencies across various coupling strengths.

## Contribution

It demonstrates that charge order frustration can enable strong electron-phonon interactions to favor superconductivity, providing new insights into the interplay between frustration and pairing mechanisms.

## Key findings

- Superconductivity is enhanced by charge order frustration.
- Strong electron-phonon coupling benefits superconductivity when charge order is frustrated.
- Quantum Monte Carlo effectively studies superconductivity in frustrated systems.

## Abstract

We study the superconductivity of strongly coupled electron-phonon systems where the geometry of the lattice frustrates the charge order by the sign-problem-free Quantum Monte Carlo(QMC) method. The results suggest that with charge order frustrated, the superconductivity can benefit from strong electron-phonon interaction in a wide range of coupling strengths.
