Quantum description of surface-enhanced resonant Raman scattering within a hybrid-optomechanical model

Surface-enhanced Raman scattering (SERS) allows for detection and identification of molecular vibrational fingerprints in minute sample quantities. The SERS process can also be exploited for optical manipulation of molecular vibrations. We present a quantum description of surface-enhanced resonant R...
