• Abstract: Quantum synchronisation has recently been proposed as a mechanism for electronic energy transfer in light-harvesting complexes, yet its robustness in the presence of strong vibrational dissipation remains under active investigation. We revisit this process in cryptophyte photosynthetic antennae using the exciton-vibrational dimer model. By comparing the quantum dynamics with classical rate equations for electronic density-matrix populations and vibrational-mode observables, we show how both environment-assisted transfer and coherent-light pumping can sustain significant energy flow despite strong electronic dephasing. Our open quantum systems (OQS) computational treatment highlights the quantum correlations between electronic and vibrational degrees of freedom that underpin synchronisation-enhanced transfer efficiency in the driven-dissipative regime, suggesting potential avenues for future investigation of solar energy-transfer mechanisms.

  We study a model of amplification of quantum transfer and making it directed which we call the quantum ratchet model. The ratchet effect is achieved in the quantum control model with dissipation and sink, where the Hamiltonian depends on vibrations in the energy difference synchronized with transitions between energy levels. Amplitude and frequency of the oscillating vibron together with the dephasing rate are the parameters of the quantum ratchet which determine its efficiency.

  We study how a large, inhomogeneously broadened ensemble of solid-state emitters coupled with high cooperativity to a nanophotonic resonator behaves under strong excitation. We discover a sharp, collectively induced transparency (CIT) in the cavity reflection spectrum, resulting from quantum interference and collective response induced by the interplay between driven inhomogeneous emitters and cavity photons. These phenomena in the many-body cQED regime enable new mechanisms for achieving slow light and frequency referencing, pave a way towards solid-state superradiant lasers and inform the development of ensemble-based quantum interconnects.

  We show that the simplest set-up of two qubits, harmonically trapped over an optical waveguide, enables the ultrastrong coupling regime of the quantum optomechanical interaction. The combination of the inherent open nature of the system and the strong optomechanical coupling leads to emerging parity-time (PT) symmetry. The $mathcalPT$ phase transition drives long-living subradiant states, observable in the state-of-the-art waveguide QED setups.
