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…
Superradiance at the localization-delocalization crossover in tubular chlorosomes
Rafael A. Molina, Enrique Benito-Matías, Alejandro Somoza +2
We study the effect of disorder on spectral properties of tubular chlorosomes in green sulfur bacteria Cf. aurantiacus. Employing a Frenkel-exciton Hamiltonian with diagonal and of…
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…
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.…
