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…
Worm-type Monte Carlo simulation of the Ashkin-Teller model on the triangular lattice
Jian-Ping Lv, Youjin Deng, Qing-Hu Chen
We investigate the symmetric Ashkin-Teller (AT) model on the triangular lattice in the antiferromagnetic two-spin coupling region (). In the limit, we…
Comment on ``Nonuniversal Exponents in Interface Growth''
Hugues Chaté, Qing-Hu Chen, Lei-Han Tang
Recently, Newman and Swift[T. J. Newman and M. R. Swift, Phys. Rev. Lett. {\bf 79}, 2261 (1997)] made an interesting suggestion that the strong-coupling exponents of the Kardar-Par…
