• Title: Engineering dipole-dipole couplings for enhanced cooperative light-matter interactions
• Authors: Adam Burgess, Madeline C. Waller, Erik M. Gauger, Robert Bennett,
• Abstract summary: We show how a metallic sphere placed within a ring of parallel dipoles generates an effective Hamiltonian that generates "guide-sliding" states within the ring system. This allows steady-state superabsorption in noisy room temperature environments, outperforming previous designs while being significantly simpler to implement. Our approach represents a powerful design paradigm for tailoring cooperative light-matter effects in molecular structures.

• Abstract: Cooperative optical effects are enabled and controlled by interactions between molecular dipoles, meaning that their mutual orientation is of paramount importance to, for example, superabsorbing light-harvesting antennas. Here we show how to move beyond the possibilities of simple geometric tailoring, demonstrating how a metallic sphere placed within a ring of parallel dipoles engineers an effective Hamiltonian that generates "guide-sliding" states within the ring system. This allows steady-state superabsorption in noisy room temperature environments, outperforming previous designs while being significantly simpler to implement. As exemplified by this showcase, our approach represents a powerful design paradigm for tailoring cooperative light-matter effects in molecular structures that extends beyond superabsorbing systems, to a huge array of quantum energy transport systems.

  We formulate a quantum optics perspective to excitation energy transport in configurations of two-level quantum emitters. We study a periodic geometry of emitter rings with subwavelength spacing, where collective electronic states emerge.

We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
