We study theoretically two vibrating quantum emitters trapped near a one-dimensional waveguide and interacting with propagating photons. We demonstrate that in the regime of strong optomechanical interaction the coupling of light to multiple emitter vibrations can lead to the formation of spatially localized multiphonon modes, exhibiting parity-time (PT) symmetry breaking. These localized multiphonon states have been interpreted by analyzing the energy spectrum in the quasiclassical approximation.
