Controlled cavity quantum electrodynamics with molecular ensembles in infrared nanocavities

Felipe Herrera, Johan F. Triana, Mauricio Arias +6 more

Molecular ensembles in confined infrared (IR) fields have emerged as a promising platform for condensed-phase cavity QED at room temperature, for the development of scalable architectures for IR quantum optics also at the nanoscale. We develop a Markovian open quantum system approach to study the dynamics of molecular vibrations in infrared nanocavities under femtosecond pulse driving, as implemented in recent nanoprobe spectroscopy experiments with polymer-coated IR gold antennas. We describe the time-domain signatures of the crossover from weak to strong coupling regimes in these nanocavities, provide mechanistic insights on the conditions for implementing coherent phase-space rotations of the nanocavity field using a tip nanoprobe, and discuss the tunable role of molecular anharmonicity as a function of pump power. Our work offers microscopic design strategies for quantum state preparation and control with emitter-nanocavity hybrids using infrared quantum optics.

Polarized linewidth-controllable double-trapping electromagnetically induced transparency spectra in a resonant plasmon nanocavity

Luojia Wang, Ying Gu, Hongyi Chen +4 more

Surface plasmons with ultrasmall optical mode volume and strong near field enhancement can be used to realize nanoscale light-matter interaction. Combining surface plasmons with the quantum system provides the possibility of nanoscale realization of important quantum optical phenomena, including the electromagnetically induced transparency (EIT), which has many applications in nonlinear quantum optics and quantum information processing. Here, using a custom-designed resonant plasmon nanocavity, we demonstrate polarized position-dependent linewidth-controllable EIT spectra at the nanoscale. We analytically obtain the double coherent population trapping conditions in a double-Λ quantum system with crossing damping, which give two transparent points in the EIT spectra. The linewidths of the three peaks are extremely sensitive to the level spacing of the excited states, the Rabi frequencies and detunings of pump fields, and the Purcell factors. In particular the linewidth of the central peak is exceptionally narrow. The hybrid system may have potential applications in ultra-compact plasmon-quantum devices.

Quantum statistics control with a plasmonic nanocavity: Multimode-enhanced interferences

Dongxing Zhao, Ying Gu, Hongyi Chen +3 more

Using a scattered field interference mechanism, we theoretically demonstrate the quantum statistics control with a hybrid system comprised of a quantum emitter and a plasmonic multimode nanocavity. Enhanced through multimode interactions, destructive interference between scattered fields from the emitter and nanocavity is able to change the photon statistics from bunching to antibunching. This transition cannot be explained by treating the plasmonic nanocavity in the dipole approximation. In some specific regions, an effective single-mode model, which is equivalent to the multimode model, is derived by simply shifting the transition frequency and modifying decay rates of the nearby quantum emitter. Superior to the closed optical microcavity, this hybrid system can be used to control the photon statistics without the need for strong coupling, and may find applications in nanoscale refractive index sensing.
