Dynamics of the sub-Ohmic spin-boson model : a comparison of three numerical approaches by Yao, Yao, Duan, Liwei, Lü, Zhiguo, Wu, Chang-Qin, Zhao, Yang

“…In order to probe the validity regimes of the three approaches, we study the dynamics of a qubit coupled to a bosonic bath with and without a local field. Comparison of the up-state population evolution shows that the three approaches are in agreement in the weak-coupling regime but exhibit marked differences when the coupling strength is large. …”

Accuracy of second order perturbation theory in the polaron and variational polaron frames by Lee, Chee Kong, Moix, Jeremy, Cao, Jianshu

“…The full polaron results are accurate for the entire range of coupling for a fast bath but only in the strong coupling regime for a slow bath. …”
