Spin and phonon fluctuations in La2-xSrxCuO4 (x = 0.22) near Qδ. S(Q, ω) as a function of energy and wave vector along a path passing through two incommensurable wave vectors Qδ = (0.5-δ, 0.5, L) and (0 .5, 0.5-δ, L) (see inset in panel a). The integration ranges are a L ∈[ − 1, 1]and b L ∈[3.8, 4.2]. …
