"Orbital-selective superconductivity in the nematic phase of FeSe." <i>Physical Review B,</i> 98, no. 22 (2018) American Physical Society: https://doi.org/10.1103/PhysRevB.98.220503.https://hdl.handle.net/1911/105072The interplay between electronic orders and superconductivity is central to the physics of unconventional superconductors, and is particularly pronounced in the iron-based superconductors. Motivated by recent experiments on FeSe, we study the superconducting pairing in its nematic phase in a multiorbital model with frustrated spin-exchange interactions. Electron correlations in the presence of nematic order give rise to an enhanced orbital selectivity in the superconducting pairing amplitudes. This orbital-selective pairing produces a large gap anisotropy on the Fermi surface. Our results naturally explain the striking experimental observations, and shed light on the unconventional superconductivity of correlated electron systems in general.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
