Quantum optics in confined geometries

A very useful concept in quantum optics is that of cavity/waveguide QED, namely, the interface of atoms with nano-photonic structures (cavities/waveguides), where the former provides the quantum nonlinearity and the latter the confinement of light. Dipole-dipole interactions between atoms, which are established via the exchange of photons, are then dramatically altered due to the nano-photonic confinement. We are interested in exploiting this principle for the design of long-range interactions and forces with applications such as entanglement generation, quantum nonlinear optics and the study of collective effects.
