                      All vibrational modes couple strongly to the charge order,
                      whereas the LuO zone-folding modes are also sensitive to
                      magnetic order and structural distortion. The dramatic
                      splitting of the LuO2 layer mode is attributed to
                      charge-rich/poor proximity effects and its temperature
                      dependence reveals the antipolar nature of the W layer
