A Combined Experimental and Molecular Dynamics Simulation Study on the Miscibility of Eucommia Ulmoides Gum with Several Rubbers

Autor: Dong-Ping Tian, Feizhou Li, Zhen-Lin Lu

Publikováno v: Polymers and Polymer Composites. 25:87-92

This paper analyzes the miscibility state of EUG blended with CR, BR, SBR, NR and NBR via Molecular Dynamics (MD) simulations performed using Blends and the Flory-Huggins interaction parameter, phase diagrams, and mixing energy. The results showed th

Correspondence between energy levels and evolution curves of fixed points in nonlinear Landau–Zener model

Autor: Bo Chong, Xuan-Zuo Liu, Dong-Ping Tian

Publikováno v: Physica B: Condensed Matter. 490:1-8

Liu et al. [Phys. Rev. Lett. 90(17), 170404 (2003)] proved that the characters of transition probabilities in the adiabatic limit should be entirely determined by the topology of energy levels and the stability of fixed points in the classical Hamilt

Upconversion improvement by the reduction of Na+-vacancies in Mn2+ doped hexagonal NaYbF4:Er3+ nanoparticles

Autor: Bo Chong, Xuan-Zuo Liu, Dangli Gao, Dong-Ping Tian

Publikováno v: Dalton Transactions. 44:4133-4140

Hexagonal-phase NaYbF4:Er3+ upconversion nanoparticles (UCNPs) have been synthesized via a co-precipitation method in high-boiling-point solvents, and remarkably enhanced upconversion luminescence, particularly in red emission bands (650–670 nm) in

A Review of Convergence Analysis of Particle Swarm Optimization

Autor: Dong ping Tian

Publikováno v: International Journal of Grid and Distributed Computing. 6:117-128

Particle swarm optimization (PSO) is a population-based stochastic optimization originating from artificial life and evolutionary computation. PSO is motivated by the social behavior of organisms, such as bird flocking, fish schooling and human socia

Critical behavior of XY spin chain with Dzyaloshinsky–Moriya interaction studied in terms of Loschmidt echo

Autor: HanLi Lian, Dong-Ping Tian

Publikováno v: Physica B: Condensed Matter. 406:1814-1817

In this paper, the critical behavior of the general XY spin chain with the Dzyaloshinsky–Moriya (DM) interaction is studied by means of a Loschmidt Echo (LE) calculation. LE presents a Gauss decay in the region of magnetic field intensity |λ| 1. T

LOSCHMIDT ECHO OF A CENTRAL SPIN COUPLED TO AN XY SPIN CHAIN WITH DZYALOSHINSKY–MORIYA INTERACTION

Autor: Han Li Lian, Dong Ping Tian

Publikováno v: Modern Physics Letters B. 25:589-597

By introducing the Dzyaloshinsky–Moriya (DM) interaction, the Loschmidt Echo (LE) of a quantum system consisting of a central spin and its surrounding environment characterized by an XY spin chain was investigated. The analytical expression of the

Effects of impurity on fidelity of quantum state transfer via spin channels

Autor: Ming-Liang Hu, Wen-Wen Zhang, Dong-Ping Tian

Publikováno v: Physica B: Condensed Matter. 406:270-274

By adopting the concept of fidelity, we investigated efficiency of quantum state transfer with the XX chain as the quantum channel. Different from the previous works, we concentrated on effects of spin and magnetic impurity on fidelity of quantum sta
