“…We note that this framework implicitly assumes an off-resonant nature of the Raman scattering, and is limited to the treatment of a single molecule. Departures from these assumptions in the harmonic limit are discussed in [8,15,39,46].…”

Cavity optomechanics aims to establish optical control over vibrations of nanoscale mechanical systems, to heat, cool or to drive them toward coherent, or nonclassical states. This field was recently extended to encompass molecular optomechanics: the dynamics of THz molecular vibrations coupled to the optical fields of lossy cavities via Raman transitions. The molecular platform should also prove suitable for demonstrating more sophisticated optomechanical effects, including engineering of nonclassical mechanical states, or inducing coherent molecular vibrations. We propose two schemes for implementing these effects, exploiting the strong intrinsic anharmonicities of molecular vibrations. First, to prepare a nonclassical mechanical state, we propose an incoherent analogue of the mechanical blockade, in which the molecular anharmonicity and optical response of hybrid cavities isolate the two lowest-energy vibrational states. Secondly, we show that for a strongly driven optomechanical system, the anharmonicity can suppress the mechanical amplification, shifting and reshaping the onset of coherent mechanical oscillations. Our estimates indicate that both effects should be within reach of existing platforms for Surface Enhanced Raman Scattering.

“…Recently, a potential hybrid quantum system for describing the strong optomechanical-like interaction was reported, involving a single vibrating molecule coupled to a plasmonic cavity [24,25]. More interestingly, this type of interaction can be enhanced to the strong coupling regime, assisted by the socalled surface-enhanced Raman scattering (SERS) technique [26][27][28]. This achievement can surely provide a potential route toward a completely different hybridization, with even higher efficiency and more feasibility [29,30].…”

We study a potential hybrid quantum system with a plasmonic nanocavity coupled to a vibrating mode of single molecule and another optical cavity mode. To explore some important and valuable applications in quantum physics, we discuss and estimate several different applications with respect to the plasmon-mediated quantum interface, the plasmon-assisted engineering of two-mode continuous-variable entanglement, and pursuing an indirect and ultrastrong molecule-photon cooperativity. In addition, governed by the relation of symmetry breaking and quantum phase transitions (QPTs), the single-molecule induced QPTs is also studied in this tripartite hybrid quantum system. This theoretical study can strongly support the potential applications of this hybrid system in the field of quantum information processing (QIP). It is believed that our investigation on molecule-plasmon-photon hybridization can not only open a new avenue towards quantum manipulations, but also provide a fresh and reliable platform to carry out many applications with high efficiencies.
