• Abstract: Easily accessible through tabletop experiments based on laser propagation inside nonlinear optical media, Paraxial Fluids of Light are emerging as promising platforms for the simulation and exploration of quantum-like phenomena. In particular, the analogy builds on a formal equivalence between the governing model for a Bose-Einstein Condensate under the mean-field approximation and the model of laser propagation under the paraxial approximation. Yet, the fact that the role of time is played by the propagation distance in the optical analogue system may impose strong bounds on the range of accessible phenomena due to the limited length of the nonlinear medium. In this manuscript, we present a novel experimental approach to solve this limitation in the form of an optical feedback loop, which consists of the reconstruction of the optical states at the end of the system followed by their subsequent re-injection exploiting wavefront shaping techniques. The results enclosed demonstrate the potential of this approach to access unprecedented dynamics, paving for the observation of novel phenomena in these systems.

  Entangled photons propagate through a complex medium such as a biological tissue or a turbulent atmosphere. Using wavefront shaping to compensate for the scattering and retrieve the two-photon correlations is challenging due to the low signal-to-noise ratio. We propose and demonstrate a new feedback mechanism that is inspired by Klyshko's advanced wave picture.

We show that subradiant emitter configurations are linked to the emergence of steady-state light-localization in the driven-dissipative setting. These results shed light on the recently reported optically-defined cavities in polaritonic lattices.

We show in exact diagonalization simulations of the one-dimensional $t-J$ model that the spinons start to populate previously unoccupied states in an effective band structure. The dependence of the spectral function on the time after the pump pulse reveals collective interactions among spinons.

• Waveguide quantum optomechanics: parity-time phase transitions in ultrastrong coupling regime [125.99533416395765]
  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.
