Distinctive orbital anisotropy observed in the nematic state of a FeSe thin film
Distinctive orbital anisotropy observed in the nematic state of a FeSe thin film
Nematic state, where the system is translationally invariant but breaks the rotational symmetry, has drawn great attentions recently due to experimental observations of such a state in both cuprates and iron-based superconductors. The mechanism of nematicity that is likely tied to the pairing mechanism of high-Tc, however, still remains controversial. …
