An ARPES and STM/S investigation of the interplay between nematicity, orbital order, and superconductivity in FeSe

ORAL

Abstract

Nematic order coexists with a myriad of iron-based superconductors, suggesting it is an important actor in the mechanism behind the superconductivity in these compounds. Many of these materials also exhibit magnetism near the nematic and superconducting phases, complicating the quest to understand their relationship. Fortunately, FeSe has no magnetic ground state and is therefore a great candidate for disentangling the interplay between nematicity and superconductivity. We performed detailed scanning tunneling microscopy and spectroscopy (STM/S) and angle-resolved photoemission spectroscopy (ARPES) studies on single crystals of FeSe to investigate the interplay between nematicity, orbital order and superconductivity.
