Momentum and Orbital Selective Nematicity in an Iron-based Superconductor

ORAL

Abstract

The emergence of unconventional superconductivity in proximity to intertwined electronic orders is especially relevant in the case of iron-based superconductors. The general picture suggests that one can suppress the dynamic fluctuations residing in the phase diagram where the chemical doping is at the optimal by applying a conjugate field. P. Malinowski et al. [1] showed that continuously tuned uniaxial strain can gradually suppress the nematic fluctuations and suppress superconducting Tc effectively. However, the underlying microscopic mechanism for this phenomenon remains elusive. In this research, we use ARPES with in-situ uniaxial strain capability to investigate the momentum and orbital selectivity of nematicity in optimal doped BaFe2(AsxP1-x)2 to provide insights into this matter.
