Weak phonon coupling to nematic quantum critical mode in $BaFe2(As1-xPx)2$

S. Wu, D. Ishikawa, A. Q. R. Baron +9

In this work, we investigate the softening of the in-plane transverse acoustic phonon driven by electronic nematicity in BaFe${}_2$(As${}_{1-x}$P${}_x$)${}_2$ using inelastic X-ray scatter…
