A Study on Transmission Mechanism of Financial Supervision with Chaos Theory

The linear rule was a general mode in the analysis of market order and financial supervision, but it frequently caused serious deviation of the market order from the supervision goal. This paper was devoted to solve the deviation with chaos model. Firstly, it substituted the operating condition of the financial institution for market order, and defined the supervision degree as a function of effective rules and realizable level. Secondly, it taked these indexes into Logistic Equation to calculate the fixed points, and simulated the complex changes of market order. Thirdly, it analyzed the characteristics of the stable numerical solution in the inter-temporal differential equation. Lastly, it explained the foresight, the exogenous, the carefulness, and the time lags of the financial supervision with chaos control theory. It deduces that when the supervision degree falls into [3, 3.554], the supervision can lead to a well-ordered market. Key words: nonlinear control, market order, financial supervision, transmission mechanism Résumé: La règle linéaire était un mode général dans l'analyse de l'ordre de Bourse et de la supervision financière, mais elle a fréquemment causé la déviation sérieuse de l'ordre de Bourse du but de surveillance. Cet article a été consacré pour résoudre la déviation avec le modèle de chaos. D’abord, il a substitué la condition de fonctionnement de l'institution financière à l'ordre de Bourse, et a défini le degré de supervision en fonction des règles efficaces et du niveau réalisable. Deuxièmement, il a pris ces index dans l'équation logistique pour calculer les points fixes, et a simulé les changements complexes de l'ordre de Bourse. Troisièmement, il a analysé les caractéristiques de la solution numérique stable dans l’équation différentielle intertemporelle. Finalement, il a expliqué la prévoyance, l'exogène, l'attention, et les laps de temps de la supervision financière avec la théorie de contrôle de chaos. Il déduit que quand le degré de supervision tombe dans [3, 3.554], la supervision peut mener à un marché bien-commandé.

Quantum correlation and classical correlation dynamics in the spin-boson model

We study the quantum correlation and classical correlation dynamics in a spin-boson model. For two different forms of spectral density, we obtain analytical results and show that the evolutions of both correlations depend closely on the form of the initial state. At the end of evolution, all correlations initially stored in the spin system transfer to reservoirs. It is found that for a large family of initial states, quantum correlation remains equal to the classical correlation during the course of evolution. In addition, there is no increase in the correlations during the course of evolution.Comment: 10 pages, 5 figure

Generation of a High-Visibility Four-Photon Entangled State and Realization of a Four-Party Quantum Communication Complexity Scenario

We obtain a four-photon polarization-entangled state with a visibility as high as (95.35\pm 0.45)% directly from a single down-conversion source. A success probability of (81.54\pm 1.38)% is observed by applying this entangled state to realize a four-party quantum communication complexity scenario (QCCS), which comfortably surpass the classical limit of 50%. As a comparison, two Einstein-Podolsky-Rosen (EPR) pairs are shown to implement the scenario with a success probability of (73.89\pm 1.33)%. This four-photon state can be used to fulfill decoherence-free quantum information processing and other advanced quantum communication schemes.Comment: REVTEX 4.0, 4 pages, 4 figures, 1 tabl
