Scanning Tunneling Microscopy Observation of Phonon Condensate (open access)

Scanning Tunneling Microscopy Observation of Phonon Condensate

This article discusses results showing that the effective radius of these phonon quasi-bound states, the real-space distribution of phonon standing wave amplitudes, the scattering phase shifts, and the nonlinear intermode coupling strongly depend on the presence of defect-induced scattering resonance.
