Quantum tricritical point emerging in the spin-boson model with two dissipative spins in staggered biases
Yan-Zhi Wang, Shu He, Liwei Duan +1
We study the spin-boson model (SBM) with two spins in staggered biases by a numerically exact method based on variational matrix product states. Several observables such as the mag…

Rich phase diagram of quantum phases in the anisotropic subohmic spin-boson model
Yan-Zhi Wang, Shu He, Liwei Duan +1
We study the anisotropic spin-boson model (SBM) with the subohmic bath by a numerically exact method based on variational matrix product states. A rich phase diagram is found in th…

Quantum phase transitions in the spin-boson model without the counterrotating terms
Yan-Zhi Wang, Shu He, Liwei Duan +1
We study the spin-boson model without the counterrotating terms by a numerically exact method based on variational matrix product states. Surprisingly, the second-order quantum pha…
