Single Mode Approximation for sub-Ohmic Spin-Boson Model: Adiabatic Limit and Critical Properties

F. R. Liu, N. H. Tong

In this work, the quantum phase transition in the sub-Ohmic spin-boson model is studied using a single-mode approximation, by combining the rotating wave transformation and the tra…
