Competition between nematic fluctuations and superconductivity in cuprate superconductors: Quantum Monte Carlo study of a three-orbital Hubbard model

Key Points

• Superconductivity is adversely impacted by nematic fluctuations in cuprate superconductors, highlighting their competing nature.
• Findings reveal that nematic fluctuations can suppress superconductivity; quantum Monte Carlo simulations support this observation.
• Observational analysis of a three-orbital Hubbard model shows complex interactions between phases at varying conditions.
• These insights emphasize the need for further studies to clarify the precise role of nematic fluctuations in superconductivity.
