Orbital-Selective Instabilities and Spin Fluctuations at the Verge of Superconductivity in Interlayer-Expanded Iron Selenide
{{output}}
Understanding electron correlation-driven instabilities and their coupling to structural phases is essential for deciphering multiorbital pairing in unconventional superconductors. We investigate Li x (C5H5N) y Fe2Se2 (x ∼ 0.6; y ∼ 0.7-0.9), a tetragonal β-... ...
