Sub-Ohmic spin-boson model with off-diagonal coupling: Ground state properties
Zhiguo Lu, Liwei Duan, Xin Li +2
We have carried out analytical and numerical studies of the spin-boson model in the sub-ohmic regime with the influence of both the diagonal and off-diagonal coupling accounted for…

Entanglement dynamics of a two-qubit system coupled individually to Ohmic baths
Liwei Duan, Hui Wang, Qinghu Chen +1
Developed originally for the Holstein polaron, the Davydov D1 ansatz is an efficient, yet extremely accurate trial state for time-dependent variation of the spin-boson model [J. Ch…

Dynamics of the sub-Ohmic spin-boson model: a time-dependent variational study
Ning Wu, Liwei Duan, Xin Li +1
The Dirac-Frenkel time-dependent variation is employed to probe the dynamics of the zero temperature sub-Ohmic spin-boson model with strong friction utilizing the Davydov D1 ansatz…
