Magnetism, orbital splitting and electron–phonon coupling of chalcogenide "11" type iron-based superconductors under high pressure

Key Points

• Enhancements in electron-phonon coupling lead to elevated superconductivity under high pressure.
• Notable magnetism and orbital splitting effects significantly alter material properties as pressure increases.
• Observational analysis on chalcogenide iron-based superconductors under high pressure explores fundamental interactions.
• Highlights the need for deeper understanding of acoustic interactions in superconductivity for practical applications.
