Finite-size scaling of the photon-blockade breakdown dissipative quantum phase transitionhttps://hdl.handle.net/21.15109/ARP/6DXXZIVukics, AndrásDombi, AndrásFink, J. M.Domokos, PéterARP2022-03-042024-10-16T14:57:46ZWe prove that the observable telegraph signal accompanying the bistability in the photon-blockade-breakdown regime of the driven and lossy Jaynes–Cummings model is the finite-size precursor of what in the thermodynamic limit is a genuine first-order phase transition. We construct a finite-size scaling of the system parameters to a well-defined thermodynamic limit, in which the system remains the same microscopic system, but the telegraph signal becomes macroscopic both in its timescale and intensity. The existence of such a finite-size scaling completes and justifies the classification of the photon-blockade-breakdown effect as a first-order dissipative quantum phase transition.PhysicsA.
