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…

Coherent-incoherent transition in a Cooper-pair-box coupled to a quantum oscillator: an equilibrium approach
Ying-Hua Huang, Hang Wong, Zhi-De Chen
Temperature effect on quantum tunneling in a Cooper-pair-box coupled to a quantum oscillator is studied by both numerical and analytical calculations. It is found that, in strong c…

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…
