“…39 These considerations complicate the use of detuning to accurately quantify the coupling constant and the efficacy of this technique remains unclear. 41 The original displaced oscillator model for describing phonon features in RIXS spectra presented by Ament et al 33 established the basis for interpreting phonon excitations for the condensed matter community and has been widely applied to experimental RIXS data. [26][27][28]42,43 Despite this widespread embrace, the model has important limitations.…”

“…not limited to) quasi-1D [25,26] and 2D cuprates [5,[27][28][29][30][31][32][33][34][35], manganites [36,37], the rare-earth nickelates [38,39], and other oxides [16,[40][41][42][43][44]. In many of these examples, the relevant modes involve the bond-stretching motion of the transition metal and oxygen atoms, which is naturally described by the SSH coupling mechanism.…”

“…If this is true, then it is essential it identify the missing ingredient. While it is clear that strong electron correlations dominate cuprate physics, there is also a growing body of evidence that electron-phonon (e-ph) interactions are also relevant [31][32][33][34][35][36][37][38][39][40][41][42][43] . For example, several resonant inelastic x-ray scattering (RIXS) experiments have found evidence for shortrange CDW order 44,45 , which appears to couple to the lattice as evidenced by anomalous softening of several oxygen phonon branches in the vicinity of the ordering wave-vector [39][40][41][42] .…”

This behavior calls for studies of the influence of the e-ph interaction on stripe order, particularly in light of the apparent sensitivity of stripes to perturbing interactions like t 0 .…”
