Zero-temperature localization in a sub-Ohmic spin-boson model investigated by an extended hierarchy equation of motion
With a decomposition scheme for the bath correlation function, the hierarchy equation of motion (HEOM) is extended to the zero-temperature sub-Ohmic spin-boson model, providing a numerically accurate prediction of quantum dynamics. As a dynamic approach, the extended HEOM determines the delocalized-...
