Superconductivity Near Magnetic Quantum Critical Points

Understanding how superconductivity emerges near a magnetic quantum critical point is fundamental to elucidate the pairing mechanism in high-temperature superconductors. Because electronic quantum criticality is a strong-coupling problem, the usual analytical perturbation treatments are generally inadequate. In this work, the researchers employ Quantum Monte Carlo (QMC) techniques to solve the problem of the interplay between magnetism and superconductivity near the quantum critical point of the iron-based superconductors. Taking advantage of the multi-band character of these systems, they developed a sign-problem free QMC to study this problem in a wide range of temperatures and parameters. The use of MSI resources is fundamental to perform these QMC calculations.
