Quantum criticality in sub-Ohmic systems with three competing terms: beyond conventional spin-boson physics
Nengji Zhou, Yulong Shen, Zhe Sun
Quantum phase transitions (QPTs) in the spin-boson model with/without the rotating-wave approximation (RWA) are systematically investigated through variational calculations using a…
Quantum phase transition of sub-Ohmic spin-boson models: An approach by the multiple Davydov D2 Ansatz
Justin Tan, Nengji Zhou, Yang Zhao
The ground state properties and quantum phase transitions of sub-Ohmic spin-boson models are investigated using the multiple Davydov D2 Ansatz in conjunction with the variational p…
Coordinately Assisted Distillation of Quantum Coherence in Multipartite System
Huang-Qiu-Chen Wang, Qi Luo, Qi-Ping Su +4
We investigate the issue of assisted coherence distillation in the asymptotic limit (considering infinite copies of the resource states), by coordinately performing the identical l…
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…
Transient dynamics of a one-dimensional Holstein polaron under the influence of an external electric field
Zhongkai Huang, Lipeng Chen, Nengji Zhou +1
Following the Dirac-Frenkel time-dependent variational principle, transient dynamics of a one-dimensional Holstein polaron with diagonal and off-diagonal exciton-phonon coupling in…
Variational dynamics of the sub-Ohmic spin-boson model on the basis of multiple Davydov states
Lu Wang, Lipeng Chen, Nengji Zhou +1
Dynamics of the sub-Ohmic spin-boson model is investigated by employing a multitude of the Davydov D trial states, also known as the multi-D Ansatz. Accuracy in dynamics si…
Symmetry and Explicit Marking of the Critical Phase in Two-Bath Spin-Boson Model
Yao Yao, Nengji Zhou, Javier Prior +1
The spin-boson model is a paradigm for studying decoherence, relaxation, entanglement and other effects that arise in a quantum system coupled to environmental degrees of freedom.…
