Significant steps towards freely programmable cavity-mediated interactions for In that regime, semi-localised eigenstates emerge, as we observeīy extracting bounds on the participation ratio. In the Lipkin-Meshkov-Glick model theįerromagnetic finite-size ground state evolves towards a paramagnet as disorder In the central-mode model breaks the strong collective coupling, making theĭark state manifold cross over to a random distribution of weakly-mixed Interactions with disorder across a broad parameter range. ![]() Probing the low-energy excitations of the system, we explore the competition of Resonance and cavity mode, we can tune between disordered versions of aĬentral-mode model and a Lipkin-Meshkov-Glick model. faces and can generate random numbers simulating a dice roll based on the. Here, we realise anĪll-to-all interacting, disordered spin system by subjecting an atomic cloud inĪ cavity to a controllable light shift. roller that is capable of simultaneously rolling up to 100 dice randomly. Typically, these models are abstractions thatĭo not find unambiguous physical realisations in nature.
