Figure: Phenomenological condition for simulating the inverted oscillator with the Dicke model. (a) Effective double-well potential (black solid line) overlaid on an inverted oscillator potential (red dashed line). The black circles indicate the critical position up to which both models agree. (b) The critical position can be translated to a condition on the number of photons which can be related to a critical time for which the Dicke model can be used as a simulator. This time is indicated by the black circle.
