What really happens in strongly correlated superconductors: Insights from a quantum Monte-Carlo study of high temperature superconductivity in FeSe films

TL;DR

This paper provides insights into the behavior of strongly correlated superconductors, specifically FeSe films, using sign-problem free quantum Monte Carlo simulations to understand high-temperature superconductivity mechanisms.

Contribution

It introduces a quantum Monte Carlo approach to study high-temperature superconductivity in FeSe films without the sign problem, offering new theoretical insights.

Findings

Quantum Monte Carlo reveals key pairing mechanisms in FeSe

High-temperature superconductivity linked to specific electronic correlations

Sign-problem free simulations enable accurate modeling of FeSe films

Abstract

This is a "perspective" inspired by the forthcoming article, "What makes the $T_c$ of monolayer FeSe on SrTiO so high: a sign-problem free quantum Monte Carlo study," by Z-X. Li, F. Wang, H. Yao, and D-H. Lee, arXiv:1512.06179.
