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…

Artifact of the phonon-induced localization by variational calculations in the spin-boson model
Zhi-De Chen, Hang Wong
We present energy and free energy analyses on all variational schemes used in the spin-boson model at both T=0 and . It is found that all the variational schemes have fail…
