Quantum phase transitions in the triangular coupled-top model
Liwei Duan, Yan-Zhi Wang, Qing-Hu Chen
We study the coupled-top model with three large spins located on a triangle. Depending on the coupling strength, there exist three phases: disordered paramagnetic phase, ferromagne…

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…
