Unveiling quantum entanglement and correlation of sub-Ohmic and Ohmic baths for quantum phase transitions in dissipative systems
Xiaohui Qian, Zhe Sun, Nengji Zhou
By employing the spin-boson model in a dense limit of environmental modes, quantum entanglement and correlation of sub-Ohmic and Ohmic baths for dissipative quantum phase transitio…
Quantum criticality of the Ohmic spin-boson model in a high dense spectrum: symmetries,quantum fluctuations and correlations
Xiaohui Qian, Congzhi Zeng, Nengji Zhou
Study of dissipative quantum phase transitions in the Ohmic spin-boson model is numerically challenging in a dense limit of environmental modes. In this work, large-scale numerical…
Variational study of two-impurity spin-boson model with a common Ohmic bath: Ground-state phase transitions
Nengji Zhou, Yuyu Zhang, Zhiguo Lu +1
By means of a trial wave function, the multi-D ansatz, extensive variational calculations with more than ten thousand parameters have been carried out to study quantum phase tr…
Fast, accurate simulation of polaron dynamics and multidimensional spectroscopy by multiple Davydov trial states
Nengji Zhou, Lipeng Chen, Zhongkai Huang +3
By employing the Dirac-Frenkel time-dependent variational principle, we study the dynamical properties of the Holstein molecular crystal model with diagonal and off-diagonal excito…
Polaron dynamics with a multitude of Davydov D trial states
Nengji Zhou, Zhongkai Huang, Jiangfeng Zhu +2
We propose an extension to the Davydov D Ansatz in the dynamics study of the Holstein molecular crystal model with diagonal and off-diagonal exciton-phonon coupling using the D…
Symmetry and the critical phase of the two-bath spin-boson model: Ground-state properties
Nengji Zhou, Lipeng Chen, Dazhi Xu +2
A generalized trial wave function termed as the "multi-D1 Ansatz" has been developed to study the ground state of the spin-boson model with simultaneous diagonal and off-diagonal c…
