Finite-temperature time-dependent variation with multiple Davydov states
The Dirac-Frenkel time-dependent variational approach with Davydov Ansätze is a sophisticated, yet efficient technique to obtain an accurate solution to many-body Schrödinger equations for energy and charge transfer dynamics ...
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 ...
