Fig. 3: Raman intensities in the A-channel with \(\gamma ({\boldsymbol{k}})=\cos {k}_{x}\) and \(\cos {k}_{x}\pm \cos {k}_{y}\).
From: Time-reversal symmetry breaking, collective modes, and Raman spectrum in pair-density-wave states
The parameters are the same as those in Fig. 2(a), (b) and (d) respectively. Collective modes, which chiefly contribute to the peaks in IR(ω) are marked.
