Fig. 4: Bimodal magnetization distribution and correlations signal the QPT at thermodynamic equilibrium.
From: Environment induced dynamical quantum phase transitions in two-qubit Rabi model
Qubits' magnetization distribution P(M/2) ((a) and (c)) and normalized correlation function C = C(τ/(βΔ/2))/C(0) ((b) and (d)). We consider two scenarios: one with g = 0.21Δ before the transition ((a) and (b)) and another with g = 0.66Δ after the transition ((c) and (d)). These calculations are performed using the WLMC method at inverse temperatures of βΔ ∈ [100, 1000].
