The temperature influence on quantum tunneling in the spin-boson model
Zhi-De Chen, Ying-Hua Huang, Hang Wong
The existing studies of the temperature effect of the spin-boson model show that the tunneling splitting will increase with temperature, no matter how weak the couplings are betwee…

Density matrix renormalization group approach of the spin-boson model
Hang Wong, Zhi-De Chen
We propose a density matrix renormalization group approach to tackle a two-state system coupled to a bosonic bath with continuous spectrum. In this approach, the optimized phonon s…

Variational Approach to the Spin-boson Model With a Sub-Ohmic Bath
Hang Wong, Zhi-De Chen
The influence of dissipation on quantum tunneling in the spin-boson model with a sub-Ohmic bath is studied by a variational calculation. By examining the evolution of solutions of…
