Time-reversal symmetry breaking, collective modes, and Raman spectrum in pair-density-wave states
Abstract Inspired by empirical evidence of the existence of pair-density-wave (PDW) order in certain underdoped cuprates, we investigate the collective modes in systems with unidirectional PDW order with momenta ± Q and a d-wave form-factor with special focus on the amplitude (Higgs) modes. In the p...
