Variational dynamics of the sub-Ohmic spin-boson model on the basis of multiple Davydov D1 states
Dynamics of the sub-Ohmic spin-boson model is investigated by employing a multitude of the Davydov D1 trial states, also known as the multi-D1Ansatz. Accuracy in dynamics simulations is improved significantly over the single D1Ansatz, especially in the weak system-bath coupling regime. The reliabili...
